Jet Performance Module Reviews

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 !

Jet Performance Programmer Reviews

Works great!

Reviewed By Michael R (BOKOSHE, OK) Reviewed for a 2013 GMC Sierra —8/9/2013 9:23 PM

Easy to program and the options are awesome! There are a lot of different options available and it only takes about 15 minutes to program everything you want. The best thing is you can remove the speed limiter. I have gained about 3-4 mpg on 89 octane. I'm going to program it for 91 and see how it goes. This is well worth the price!
