Finally the response is still there. Soon a custom toon will be added for even more out of the ecotec 3 v8! Love the tuner.

GMC 6.2 L 8SP be forewarned

Reviewed By sky b (FAIRFIELD, CA) Reviewed for a 2015 GMC Sierra —8/21/2015 8:39 AM

Overall great but doesn't work with the 8 spd trans. 2015 1500 Denali 6.2L. the workaround is to choose manual transmission in programming, but obviously you aren't getting any shift point adjustments or anything. Another note is that I have a lift and 35" tires, but the speed calibration had to be set to 33 to be accurate. "Luckily," we have the radar signs in our neighborhood, so I could take a few tries and get it dialed in, otherwise speedo would have read fast, not slow.

looks dont matter

Reviewed By oscar a (Norfolk, NE) Reviewed for a 2005 GMC Yukon —5/4/2012 7:05 AM

So I bought this tuner not knowing anything bout it. I was worried I might not know how to properly install tunes and mesure paeameters. Well after a while of research I found out how to installl tunes I tried the 87 octane tune. Right away I felt a huge difference my truck was awake my acceleration was different more responsive. So then I did more reseach found a guy by the name of lew or diablew tunes predator gives u the option to install custom tunes and diablo.com gives u the information you need to find people that can make a custom tune for ur car/truck. I found lew won't go into much detail but he tuned my truck with balls. There is so much thing u can do with this tuner if u have mods on ur truck a custom tune is for you. Or even stock vehicles can enjoy this great product.
