Jet Performance Module Reviews


seems to do the job

Reviewed By jeff l (POTTSTOWN, PA) Reviewed for a 2003 GMC Envoy —8/22/2013 10:56 AM

I purchased this for my 2003 Envoy XL 4.2L V6 for towing mostly. I also have a K+N cold air intake. My wife and I have noticed a difference in shifting gears, lower RPM's in regular driving and towing, more power where it needs to be, but have not seen a drastic change in fuel economy. Have only had it installed now for 3 weeks. I would certainly recommend this to anyone.

Installed on 2006 Sierra

At first I wasn't sure if it really was working cause I couldn't really see big changes but after about a month I noticed the mpg gains. The power increase was quite amazing too. I feel this is a great product and as they say" you get what you pay for ". Already thinking about upgrading to the IQ.

Edge Juice with Attitude CS or CTS Reviews


good i guess

Reviewed By Michael L (Syracuse, UT) Reviewed for a 2008 GMC Sierra —4/27/2011 10:02 AM

Intalled easily with juice unit but display unit is a pain to get stuck to dash if you've ever put anything on the dash. There are SOME things it can monitor but you only get to choose between SOME of the things the onboard computer can see. Can't figure out why they wont let you monitor anything the gas version can as well on the diesel. Gas mileage has only increased on freeway and stayed about the same in city. You can definitely feel the difference in mode 3.
