V4 a thing of the past!

Reviewed By Timothy L (FORT WAYNE, IN) Reviewed for a 2017 GMC Sierra —4/12/2018 4:20 AM

Purchased my 2017 GMC Sierra just a few weeks ago, saleslady didn't tell me anything about the truck going into V4 mode. After noticing power drops and almost getting hit waiting on it to switch out of the V4 mode, I had to read the manual. Educated myself and hated the V4 mode! Found this unit while browsing on the internet and purchased here at This unit has allowed me to fall in love with my GMC Sierra. What a difference!

TruXP Xtune Plus Performance Tuner Reviews

Hard to beat for the money

Reviewed By jason s (Houston, TX) Reviewed for a 2016 Chevy Silverado —4/9/2018 9:06 PM

I added larger tires to my 2016 Silverado. I wanted to be able to input proper tire size for the vehicle. This device made that easy. I was also able to turn off the afm, which is nice. Surprised at the amount of adjustments that are available for shift points. Something beyond my needs so I left it alone. Very pleased for the money spent.
