Does the job

Reviewed By Bobby V (Edmond, OK) Reviewed for a 2010 GMC Sierra —1/20/2015 6:11 AM

Have you finally had enough of the V8 you paid for switching to a V4 "under light loads"? Don't want to spend a ton on a programmer? Then buy this device. I've had it for a couple of weeks and have been very pleased with the results.

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.

Glad I purchased.

Reviewed By Robert M (Pocono Pines, PA) Reviewed for a 2011 GMC Acadia —2/4/2012 10:49 AM

I looked at a few other types. Glad I got this as it fits perfectly below my radio and the Adjustable light/color setting are terrific. Also having it automatically go on/off, removes the Possible battery issuer. Haven't tried all functions, sure they will be good. Check reviews of all items before you buy. It really helped steer Me to this product.
