Trey Seamore, SC

“I can't thank you guys enough for these tunes.  I just beat a GT350 in my GT. After he pulled over and asked what I had done to it."

Justin Harts, IL

"They tuned my 15 GT 6MT N/A, W/Paxton making 830 Wheel, also W/Whipple and now a single 78/75 turbo w/boost leash, Sia Li dual return Fps, 1200CC injectors GT350 TB and E85 that runs great and is fast AF.  I've gapped supercharged corvettes, whipple terminators, a TRX on race fuel, a nitrous 200 shot gen 3 10R80 whipple scat packs with cams and the list goes on... The car made over 1000 wheel and blew the tranny so I just upgraded that and they dialed me in for 2 more lbs of boost. Highly recommended for boost tuning 10/10."

Collin Cordial, Guam

“They will give you outstanding service and great tunes. They worked with me while I was stationed on the opposite side of the world and been 15 hours ahead of them and they are still always available. Highly recommended!”

Mason Dyess, TX

“I met P1 after making a post about another tuners customer service.  They were able to get me 3 outstanding tunes in 3 hours that have made my car feel like a dream car. Their 93 and flex fuel tunes are incredible and if you're feeling spicy ask for the burble. I would recommend them to everyone 5 out of 5."

Scott Hanger, IN

"I couldn't be happier with my experience tuning my 17 GT. They are knowledgeable and answered my numerous questions. I wasn't happy with my tune from one of the "big guys". P1 always answered in minutes.  Every aspect of the car is better, start up, idle, shifting and acceleration. I'd recommend them to anyone that asks about tuning."

Chase Jasmer, MN

“I purchased a 96 4.6 V8 and it needed more power. P1 was quick to respond and revise. The car went from 2nd gear burnouts to 4th gear now.  Car whipped donuts so hard the ball joint popped out. I highly recommend P1 Tuners for all your tuning needs.”

Artice Schooler, IL

“Honestly my best experience with a tuner hands down, they answered every question.  Had my 19 GT running smoother than my previous tune and even more powerful. They helped me data log since I am new to this as well. I couldn't have asked for a better experience."

Anthony Koch, NY

"They really did an amazing job on my 5.0.  They continued to fine tune even after my dyno session.  I made 400 Wheel on my stock 2015 6R80."

Cameron Barton, CA

"I was having trouble with Bama and P1T got it right the first time. They got the tune out to me same day and keep you updated on the details of what they are modifying.  My car runs great now 10/10.”

David Pawlowski, MN

"Got tunes to me same day, and revisions have been same or next day from me sending out at 11 PM lol. Ghost cam option is pretty cool.  Car is 18 GT 6MT mods are MXP intake, 87MM TB, headers. Would def recommend."

Joshua Harris, TX

"I absolutely recommend P1 for any of your tuning needs!  The turnaround is insanely fast I got 3 tunes built and sent within hours of contacting them. They allowed me to drive and data log to fully customize the files to ensure maximum performance and drivability."

Brandon Grenier, CT

“From day one of my build (Kenne Bell SC 97 Cobra) they have been by my side all the way until tuning all remote.  We tuned it on E85 and they walked me through all the details which gave me amazing confidence.”

Hudson Brown, GA

“Absolutely great to work with. Emailed me 4 tunes in less than 24 hours for a great price. THey made sure my data looked correct and explained everything. Highly recommended 10/10."

Jacob Babb, FL

"Nothing but amazing, highly recommended. They walked me through the entire process.  If your looking for an excellent tune thats a simple process I would go with P1T."

Ernesto Otero, IL

“I was first introduced through a GT350 FB group.  I had a simple question about running E85 and not only did they help answer that, they talked with me about my goals and wrote a custom tune for E85 and 93 that was worlds apart from what I was running. Highly recommended 10/10.”

Juan Polito, FL

“They dialed in my 2020 GT 10R80 on the dyno when I was still in NY and I made 474 wheel exhaust only. Highly recommended 10/10!"

Josh Ropte, IA

"Marc took care of me when I was having issues and got me up and going with a custom tune in just a few hours. Process was super easy and I'm running great. Highly recommended! Can't wait to come back for that E85 tune next."

Drake Kosky, IN

“Marc was a huge help when I had problems with tuning my gen 3 coyote!! Started with a bama tune and the P1 tune was a night and day difference! Definitely recommended!”

Aaron Harperjr, MA

"I 100% recommend P1 Tuners. Marc, my specific Tuner was awesome, he treats you like family, like if your brother was to tune your car. Marc treated me like a paying customer for a month or two while I went back and forth thinking about what I wanted, before I spent the money. He walks you through everything, and he was more excited to tune my car than I was to get it tuned. If you’re getting your car tuned by someone, choose p1 tuners, and ask for Marc Reimer."

Shelby Nero, IL

"Marc worked extensively with me, to get my 2019 Mustang GT dialed in on a 91 tune. He was willing to work with me day or night and now I feel like I have a completely different car. Would recommend him to anyone looking for someone who cares more about the customer than the money and am looking forward to building out my E85 tune with him."

James Taylor, NC

Marc was extremely helpful guiding me through the tuning process, he gave me insight and allowed me to follow along the process going above and beyond as a tuner and putting incredible trust in me as a customer. He also has my E85 s550 running like a beast 10/10 experience and will be looking forward to working with Marc and P1 on all my tuning needs.

Edwin De La Paz Jr, NC

“Mark did a great job retuning my car from my previous tuner wish I got in contact with him sooner will worth the money.."

Austin Ferguson, OH

"Exceptional service ! Mark did awesome on my tune ! Stayed up late hours and walked me through every step of the way. I would recommend him to anybody. Thank you for all your help and continued support !"

Brayen Gaiter, AL

“Exceptional Service!!! Also, they turned my 2015 5.0 Mustang into a beast!! I’ll be telling everyone about them!”
