Great, Clean Power. Best Customer Service.

I went from a bully dog programmer to the 60hp PPEI tune and it’s night and day difference in throttle response and power. Also doesn’t blow as much smoke which is great. Had a few problems installing the tune but PPEI customer service is the best you can ask for and fixed me up right. This is the second truck i’ve tuned with these guys and i’ll never buy elsewhere. Thanks PPEI!

Holy Crap

PPEI is above and beyond. Had Smarty and was tired of the black smoke. PPEI gave me enough horsepower to show off and do the every day things I need to do with lower EGTs and quicker response. Customer service was 100%. Shout out to Zach. Walked me through everything so that a 10 year old could program my truck. WOW!!!


Couldn’t be more satisfied. Clean tunes and awesome customer service
