    "I got my PCU back this afternoon and installed it back in my truck, at the twist of the key it snapped back to life like a pit bull dog straining at its leash as an intruder enters its masters space of security!
    In an instant it tied all my add on's in together turning my 160k mile 2006 GMC Sierra 1500, that felt a bit sluggish, into a brand new aggressive truck willing to take on anything, with shift points that are smooth but felt each step of the way. Throttle response is impressive and tight as is the rest of my 5.3 V8 automatic. My truck literally feels like a brand new truck, full of aggressive life and ready to serve. Thank you so much for your product for it definitely made an impressive difference in my whole truck."

    "Everything is working 100% excellent, thank you so much for everything you have done and not giving up, and from that, that’s why your company is the best in tuning and customer satisfaction and again thank you for everything you have done. You could have gave up, but that shows me your true ability to take care of a customer that goes a long ways."

  • Steve S.

    "Thanks for a good product. I really could feel the difference in power. If there is someone out there wondering if it is worth it the answer is, YES. It really gets up and goes now."
