My Yukon is way more responsive now than ever before. I have not changed the oil yet to compare how much was not used since installing the range.

This is by far the first, best upgrade I've made to my Denali! Fairly easily installed (no thanks to GMC) and my 5.7 Vortec started right up with no codes. I experienced immediate increases in throttle response and overall power and drivability. Unbelievably, after a week or so of driving the vehicle, the power and responsiveness approved again! Puts me in mind of the old EPROM chips. I highly recommend this product to anyone looking for low dollar extra horses and low-end torque !

WoW! I went from 12.5 to 16 in the city, using 91 oct on performance mode, shift points firm. Versus 87 oct in stock. It's how you drive it that matters. The driving coach is way cool. And it's fast too!
