I installed this on my 07 sierra. Simple as can be. I've noticed more power and acceleration. Transmission seems to shift smoother. Great investment.

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 !

Installation in my '06 Tacoma wasn't a "no brainer" despite the fact it's a plug and play scanner. I made a slot for it in one of my "cubby holes" using a sheet of 1/16" ABP plastic. Still learning everything that the scanner will do but am pleased so far.
