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.

It does what I expect and more

Reviewed By Erik R (Anza, CA) Reviewed for a 2009 GMC Sierra —5/16/2015 1:43 PM

Dang. I didn't realize there was a 500 character limit. So I will keep this short and sweet. Power 5 Ease of use 5 Tuneability 4 Instructions on what does what 3 If you don't care about your 0-60 times and yada yada buy this tuner. Oh! Do NOT adjust your tune if you have smog/state inspection coming up. They don't tell you that if you adjust parameters you will fail. It took about a week for my truck to go through the "GM cycle". Great buy, autoanything rocks
