Hypertech Max Energy Programmer Reviews


2004 Jeep Liberty

Reviewed By George Y (STAFFORD, VA) Reviewed for a 2004 Jeep Liberty —2/21/2016 1:55 PM

Programmer had to be updated but otherwise easy to install. I've noticed some slight pinging at part throttle and engine knock at full throttle. I am going to contact Hypertech and see what they say about that. Fuel economy is better but may need to run premium fuel. If you are considering this product carefully read there web site about model specific features. For example unless it mentions shift firmness or adjustable shift points you are going to have the stock settings for an A/T.

Better than Bully Dog

Reviewed By Jonathan W (Killeen, TX) Reviewed for a 2015 Chevy Silverado —6/21/2016 4:47 AM

I had bully dog before this one and it took me and my truck through the ringers. This product I should have stuck with since my first use in 2004. I love this product and will recommend to anyone.

Worked well!

Reviewed By Shane P (MOORE, OK) Reviewed for a 2015 Chevy Silverado —6/10/2016 4:39 PM

Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.
