Decent Performance

Reviewed By Keith F (Doylestown, PA) Reviewed for a 2009 Jeep Liberty —4/5/2012 10:57 PM

After a discount and free shipping, I paid about $225. I can feel a difference with the chip and premium fuel as it recommends, but $225 was a little too expensive. I also have an intake and a muffler to help with air flow, so I get a little more power out of the chip, but no gains in MPG.

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.

Reviewed By Thomas E M (CALDWELL, ID) Reviewed for a 2004 Jeep Liberty —7/7/2014 9:33 PM

Using Scanguage to tshoot codes and to help better monitor driving style and engine situation has saved me enough on fuel to buy the second one.
