Definitely keeps my Sierra in V8 mode. This might be a little unbelievable but I actually get about 4 more miles per gallon. Plus no hesitation anymore from switching back and forth from V4 to V8.

Can't find another tuner near the same price. I have only used the stock with options to change tire size and AFM and it worked easily for this. Menus were simple and easy to navigate. Much cheaper than getting these changes done by a dealer. I had one small issue with an error code when first installing and technical support got it figured out and updated quickly.
