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.

DiabloSport Predator P2 Tuner Reviews

2006 dodge charger r/t

Reviewed By Leroy W (forestville, MD) Reviewed for a 2012 Jeep Liberty —11/8/2011 9:07 AM

When I first got my preditor about a week ago, I had to go on line to update it. I found that to be confusing but I got it done. Maybe I was expecting more from the preditor since i already onw a programmer from hypertech but I have'nt noticed anything different from the performance tunes. I even custom tuned my charger with no difference. Wish i could say more positive things about the preditor.

Hypertech Max Energy Programmer Reviews

limited for a 3.7L

Reviewed By James S (San Antonio, TX) Reviewed for a 2010 Jeep Liberty —4/4/2015 3:23 AM

It's a nice unit but you literally have 4 options. Fuel, rpm, fan temp, tire "speed rating." It did help slightly with my fuel economy, I definitely feel the torque about half throttle. Can't say much more other than I really wish it had a setting to adjust for other than stock tire sizes and not just tire speed ratings. Hypertech has notoriously not responded to the question of why it's not an option for 3.7 liters and auto anything delivered the unit 2 days late.
