I really expected it to be more complicated. I opened the box, plugged it in the OBD II port and started the truck. That's it. Done! No more 4 cyl. mode. I'm not sure why they put LED lights on it. They illuminated my ankles at night so I had to put a piece of electrical tape over them, problem solved.

Edge Evolution CTS2 Programmer Reviews


Good Programmer, did exactly what i bought it for

Reviewed By Henry K (Celina, OH) Reviewed for a 2005 Chevy Avalanche —9/13/2016 8:23 PM

AutoAnything had fast, on time shipping and great packaging. Had a little trouble installing the programmer due to some aftermarket mods(remote start). Eventually got installed by removing some fuses and is now simple to do when switching to a different tune. Saw instant gains in MPG, around 2.5 MPG on economy tune. Also some noticeable torque, power, and acceleration gains on economy which is what I have it on most of the time. Bought mostly for better MPG and did just that.
