"Called Jason about a issue I had with a truck. Did everything he could until it was correct no excuses. Truck runs better then ever. Highly recommend."

"10 outta 10 would definitely do business with them again, Jason kills it with the laptop, dude knows what he’s doing, thanks again man!!"

"I called Jason after a referral from someone . I had previously got a tune after putting long tube headers on my 17 Camaro where I didn't feel the power I hoped for and had a engine light that would not come off (never had engine light on before heading/tune) Jason got me in the same week and was returned to me the same week. He got my car running the way I hoped it would and without any lights in the dash! I highly recommend doing business with Jason."

"10/10 Highly recommend. I just had a motor put in on my truck and had Jay tune it and works perfect no problems. Definitely knows what he is doing and highly recommend. Fast very reliable and a ton of knowledge!!! I will definitely be doing business here again in the near future"

"Jason happily agreed to do a tune and said if I did a dyno run before my parts were installed the money would go towards the tune afterwards.So I had a dyno run to see what hp it made before parts install.After parts were in stalled and I needed the tune,no more Jason! I left 3 text and he would not reply! Very unprofessional ! What a waste of time and money!"
