"FRIENDLY, HELPFUL, AND PATIENT"
"Don and his guys are great! Today was our first time out to get our 600 Micro Sprint tuned. Super friendly, helpful and patient, they explained everything they were doing and why. Not to mention they got us a few extra HP and peace of mind knowing our engine is running as best that it can. Thank you guys!"

"THE BEST"
"I had an amazing experience with Guhl Motors. I had an engine that needed some fine tuning. I removed my ECM and sent it to Don and the team Monday and it arrived at his shop Wednesday. I literally received my flashed ECM back the very next day! That is service! Reinstalled it and is exactly as I expected it. Thanks so much Don and team. You guys are the best. I definitely recommend them."

"I had an amazing experience sending in my ECU in to get it flashed. Got to talk to Don Guhl, told him what I wanted, got it back home, and that thing takes off like a rocket. Great throttle control and runs amazing. No problems, thank you so much for relieving my problems with my engine. I will spread the word!!!"

PENNY"

"INCREDIBLY KNOWLEDGABLE STAFF"
"Absolutely awesome in every way. Don is an absolute genius and a total gentleman. He explained everything every step of the way. His staff is equally awesome. They're all incredibly knowledgeable and extremely friendly. After having my brand new ECU flashed at Guhl Motors, there is without question a "HUGE" noticeable difference in every way. Much more power. Very smooth. Pulls longer and stronger. It's totally different. I couldn't be happier. Great job. Thank you."

"QUICK TURNAROUND"
"I'd like to thank Don and his guys for the quick turn around on a a wiring harness and throttle bodies. Guhl Motors found the parts I needed on eBay so I didn't have to order them, then shipped them to themselves to be converted. They did all this in record time to get me going again. Thank you to Don and the gang at Guhl Motors."
