Amazing, Inexpensive Real Power!

Reviewed By Robert L R (VALLEY, NE) Reviewed for a 2000 GMC Yukon —2/12/2016 9:15 AM

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.
