seems to do the job

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.

Since I installed the CAI, SIDO exhaust, Larger tires... I wanted to adjust for speedo & Odometer. Also wanted shift points adjusted. This device did all I needed. I was not looking for custom tuning. I am very satisfied with the results

Edge CS Evolution Programmer Reviews


Project Silverado

Reviewed By Frank Y (Kilgore, TX) Reviewed for a 2006 Chevy Silverado —5/18/2015 9:14 PM

Ordered Edge CS Evolution Programmer with matching gauge housing. Easy to install, looks great. Four levels to choose from. Nice gain if your willing to use premium fuel. Have modified exhaust & intake so it really pulls better. Nice surprise when I took off the speed limiter. Now have to put on speed rated tires, from 95 to 120 & still pulling. Built in OBDII reader really sweetens the deal. Wish I'd ordered it sooner.
