GoodSpeed Performance in
Scottsdale (AZ)

Awesome service. Came in for an ECU flash and was done in under an hour. Friendly and knowledgeable staff, highly recommended.

Great experience all around and everyone i met was nice and knowledgeable. Quick turnaround and the exact tune I was looking for. Called another shop closer to where I live before going there and they wanted to charge nearly 2X the price Goodspeed charged for the same tune. I'll be back if I get power hungry again.

Amazing work! First time getting a car tuned and they were super informative and helpful. Ryan did a great job with keeping me in the loop, overall very happy with them and the experience

I can’t thank Ryan at Goodspeed Performance enough. Even though I wasn’t a paying customer and hadn’t done any work with them yet, he still took time out of his day to help me track down my ECU after another shop stole it and completely ghosted me. He didn’t owe me anything, but he stepped up, made some calls, and ultimately found it—giving me serious peace of mind during a super stressful situation. It’s rare to find someone in the car community who shows that level of integrity and professionalism without expecting anything in return. Ryan went above and beyond, and because of that, Goodspeed has 100% earned my business going forward. Highly recommend them to anyone who wants honest, knowledgeable people working on their car.

Wonderful working with Brian and Ryan here. They got me in last minute which I super appreciate. Even the day before thanksgiving. They tuned my car and have done nothing but good work on it. Thank you guys! Will be back!

I’ve been a customer of GoodSpeed for over a decade and they are simply the best. The team is knowledgeable, helpful and always looking out for my vehicles best interest. They are so good when I move 90 minutes away I still go to them for all my vehicles needs!

This is my third time here and I’m even more impressed than the last time. Just had a cat back exhaust installed on my 2020 Challenger and I’m very impressed with the results. The customer service and efficiency is the best I’ve ever experienced. I dealt with Ryan today and he was very professional. Looking forward to bringing my car back for the next step!

Asked for an installation on a grill I wasn’t comfortable with installing and they were super quick and did a great job with the installation.

Found Good Speed Motors after actually looking at a GLI for sale just like mine(Pyrite Silver) and the seller had done quite a bit of mods with this shop. Work Good Speed did on my car. 1.APR Stage 1 Tune(Another APR Dealer) 2.DO 88 Intake 3.New Continental Tires 4.Alignment 5.New Grill Upper & Lower & Black Grill inserts 6.APR Intercooler 7.New Cross Drilled Rotors & Red EBC Brake Pads My car was mechanically decent when I bought it two months ago(2021 Jetta GLI Autobahn), however the cosmetics were horrible so needed everything from all the mods to a correction detail also a new windshield. Good Speed handled it all for me so want to thank Ryan who estimated and ordered everything and Jon also Brian. Also thankful for good work by the techs (Didn’t get their names) so took care of them and my wife made Banana Cupcakes to show appreciation. Moved here from Bay Area CA a while ago and really glad I have a go to shop now, see you for maintenance in a bit so my wallet recovers lol.

I’ve been meaning to leave a detailed review here after the GoodSpeed team did a fantastic job on a large build for my 2007 WRX STI. By no means was this a small job, and Joe and his team were extremely responsive, knowledgeable, and thorough as we walked through this detailed build to accomplish the goals I had outlined. Everything from the installation of complete motor work, too many supporting mods to list, fuel system upgrades, larger turbo, cooling mods, tuning, etc. were done in an extremely professional manner. If rock solid work, stellar communication, and knowledge from prior experience on these cars all matter to you, I would highly recommend calling Joe and his team at GoodSpeed Performance to discuss your Subaru build, no matter how large or small. I’m having a blast breaking the motor in, and want to give a giant THANK YOU to Joe and his team. I know who to call first for any of my future performance vehicle related needs. ?

Goodspeed Performance is truly one of a kind. While the cars are considered family for us, the staff quickly became family too. We first heard about them when we were moving from Massachusetts to Arizona, and their reputation is loud and clear all the way from the other side of the country! From the moment we walked in, we felt the passion, care, and pride that the team pours into every job they've done for us so far. They don’t just treat vehicles as machines...they treat them as part of your life story, and they go above and beyond to make sure you and your car are taken care of in the best way possible. Their knowledge, craftsmanship, and attention to detail are second to none, but what really sets Goodspeed apart is the heart behind the work. We plan to continue to work with them with every car in our collection and trust them with each and every single one of our babies. This is not just a performance shop; it’s a place where relationships are built, trust is earned, and dreams on four wheels come alive. I can’t recommend them enough. If you want world-class expertise paired with genuine people who care about you and your car, Goodspeed Performance is the only place to go in Arizona. I'd even ship my cars here from other states because they're THAT good!

I had an APR stage 1 tune and turbo inlet pipe installed recently by Goodspeed. The process from start to finish was as smooth as can be, easy communication and timely scheduling. Very professional shop offering top notch installation and service, as well as pricing. Very happy with the results and service!

Jon Firpach has in-depth understanding of these vehicles and is thorough in his explanations of options. There were things I was told that I could do from other shops and read about on-line, but it wasn't until I spoke with Jon that I was informed those mods are very model specific and it would be poor investment to purchase and install these things as the software management systems do not exist to support it.

Called the shop to see if they can tighten up an intercooler pipe for me and they were able to fit me in real quick. One of the guys just came out to the parking lot and secured it for me and I was on my way. They were quick and easy and nice people. Cool shop too.

Great staff. Very friendly and knowledgeable. I had an engine rebuild and tune performed here and the results were awesome. They also corrected issues found in my fuel system. Their explanation of work performed and pricing was transparent and fair

To keep it simple, the people at GoodSpeed run a shop how a shop should be run: easy communication, fast responses, quality work, and fair prices. After being fed up with some of the other shops in the area, I came across GoodSpeed and decided to give them a call to see if they could reinstall a rear diffuser for me. They promptly invited me in, and within twenty minutes of my original phone call, I was in the store as they assessed my car. Everybody that I interacted with in the shop was very personable, and I could immediately tell that they are the type of people to go above and beyond for their customers. When I came back a few days later for them to work on my car, they got to work right away and got me in and out of the shop in a timely manner. Obviously, their work on my car was excellent, but beyond that, the thing that stuck out to me most was their customer service, which is far superior to that of any other shop I have tried. My experience with GoodSpeed could not have gone better, and I would encourage anybody who is looking for a flawless experience to give them a try as well.

I brought my TRX here to have numerous aftermarket mods done in one day. They got everything done in a timely manner. I did end up having an issue where my accessory belt threw shortly after I picked the truck up. I called after hours and was helped and even offered a complimentary tow. That didn't end up being necessary but I appreciated that level of service! They ended up getting everything perfectly fixed early the next day. Now everything runs how it should and all the mods were done very well. Thanks to everyone at GoodSpeed!

I was trying to leave a new review, but I believe Google replaced my previous post instead of adding a new one. Bottom line If you’re serious about your build and want a team that treats your car like their own, this is the place. I’m beyond satisfied and will continue trusting them for every stage of my C63s build.

I can’t say enough great things about the team at Goodspeed Performance. They recently completed an installation of my aftermarket exhaust manifolds for my Mercedes-AMG C63S, and I’m beyond impressed with the results. If you’re looking for a performance shop that takes pride in their work and understands high-performance European platforms inside and out, Goodspeed Performance should be your go-to. I’ve relied on Goodspeed Performance for the past 4–5 years, and they continue to exceed expectations with every visit. I’m looking forward to the next stage of my build with them.

This place is trash! Do not take your car here. Currently selling my 2009 CTS V and the buyer wanted to have the car looked over before buying it. Buyer is from Tucson and found this shop online and so I agreed to take the car here. WORST DECISION EVER!! They took a full day to do a look over of the car which consisted of doing a compression test, checking fluids, service lights, leak down test, suspension. Was told my car was going to be done by 1pm for the guys to pick up and was not completed till 530pm. I was then informed by the buyer that he received the report from the shop and that there were a list of issues(out of nowhere) and that the compression test failed. This being completely untrue and I had just recently had the block rebuilt and had zero issues with performance. When I picked up the car the next day, I wanted to ensure everything was put back together correctly and that there was no damage…well there was. After inspecting the car, while still at the shop, I noticed that most of the installation boots for my spark plugs were ripped. When I went back into the shop and informed them of to, they came outside to loom and was told that the car is old and they are brittle which is why they ripped, and that they had their “most experienced” tech on it so it was not their fault. That’s not possible when I just replaced them in March of this year. Second, they scratched the hell out of my paint where the ice tank is located. When I asked for some kind of compensation for the damage, they basically told me is was my issue and that there was nothing they could do. I took my car to a shop I trusted to check on the “failed” compression test only to find out they miss threaded and stripped a spark plug when putting it back in which is the cause for the failed compression test. Moral of the story, DO NOT USE THIS SHOP! They will damage your car and then take zero responsibility for the damage they cause.

I have to say this is my second car I have taken to Goodspeed Performance Lab. I highly recommend Goodspeed Performance Lab. The knowledge and professionalism shown by the staff are one of the best. I took my AMG C63 for stage 2 and a tune. My car's performance doesn't disappoint. I highly recommend John and Luis the rest of the staff

This is my go to shop for custom maintenance, installations, aftermarket parts and accessories for my 2024 C8 Z06. Godspeed goes above and beyond to deliver the best customer experience.

Recently had an HKS Supercharger installed in my BRZ. 10/10 flawless work. Shoutout to Luis, he took great care of me from answering all my queries to ordering and installing the sc. They made the whole process easy for me and the job was done in a timely manner. Will definitely be coming back for future mods.

Great team, quality service, and amazing work! They were patient with me throughout my mod process in addition to explaining exactly what was done.

Thank you to Jon for turning my 911 turbo S into a wicked beast! The car is truly transformed. It’s insane and so much fun! Anyone with a Porsche that wants to take the next step absolutely give Jon a call. He will help you through every step of the way. He’s meticulous and his years of knowledge really show when building a complete cohesive package. Thank you again! Amazing!

A lot of good performance parts if you want to upgrade your vehicles I just went the to do the alignment on my 1998 BMW M 3 they did a great job ?

Goodspeed is the best in the business by a mile ! Purchased a 2017 Camaro ZL1 and they were the first people i contacted. I wont have my car at any other shop in the valley. Jon and his team are ahead of the game and im happy i found them. The shop stays full because they take care of their people. Not sure if this is the right shop ? Call in and talk to them. All of their staff is friendly and happy to help. Cant say enough about this place.
