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.

Hypertech Max Energy 2.0 Programmer Reviews


2014 GMC OIL SAVER

Reviewed By George C (ROANOKE RAPIDS, NC) Reviewed for a 2014 GMC Sierra —5/24/2017 7:40 AM

I bought the Max 2.0 because other reviews had said their trucks had stopped using oil when the 4cyl program had been turned off. I have run this program now for close to a thousand miles and haven't used any oil with the engine running on 8 cyl all the time. Gas mileage has remained about the same as before, I haven't noticed any problems with the Max 2.0 programmer. My 2014 GMC sierra has a lot more horse power running this programmer .
