The old gas hog!!!

Reviewed By Steve G (SHAWNEE, KS) Reviewed for a 2004 GMC S15 Pickup —6/13/2015 12:07 AM

I like the programmer, I wish it could do more to help or improve the gas mileage on my truck! 16 MPG before the installation, and 18 mpg after the installation.The increase was and is appreciated, I would like 24 or 25 MPG even better.I guess you can only do so much, with what you have to work with.

Does what it says

Reviewed By Taylor M (MESA, AZ) Reviewed for a 2014 GMC Sierra —1/26/2015 9:06 PM

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!
