2005 Liberty Renegade w 40,000 miles

Reviewed By Kurt M (Longwood, FL) Reviewed for a 2005 Jeep Liberty —10/27/2011 4:58 AM

This was installed along with an Airaid TB spacer and a K&N intake. As far as power it is kinda noticable (No wow factor!) what I did notice was the improved smoothness of the engines power curve. I'm pretty sure my fuel economy has dropped by at least 1.5 MPG and will verify this weekend and repost this review. I will remove each item one at a time to discover which one(s) caused it, although I'm pretty sure it's the chip and I did all this to improve my MPG's. I have 33 years experience turning wrenches and do it for a living (Took me 15 minutes to install) and must say the install instructions are generic and poor at best for a weekend wrench turner. I will give AA a A+ rating for their customer service.

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.

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.
