Hypertech Max Energy 2.0 Programmer Reviews

Easy to use

Reviewed By adam e (HILLSBORO, OR) Reviewed for a 2016 GMC Yukon —3/28/2017 11:00 AM

Device was very easy to use. Took a few times for computer to recognize to perform updates. Other than that no problems. Vehicle seems to be working great with updates.

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 !

Hypertech Max Energy Programmer Reviews

Exactly what I wanted

Reviewed By Ned R (Granbury, TX) Reviewed for a 2012 GMC Yukon —2/20/2015 9:23 AM

My 07 Avalanche is used for most of our travel as well as pulling our 21' travel trailer. I was very disappointed in the Avalanche power above 50 mph. The programmer has allowed me to pull the trailer about 10 mph faster and has increased my fuel mileage by 1 mpg. I did also add a K&N air intake. Now pulling the trailer is pretty easy. I also get improved mileage around town.
