Over a 1 MPG increase AND on 87 octane!

Reviewed By Sean J (Belle Chasse, LA) Reviewed for a 2005 Cadillac Escalade —9/2/2013 8:14 AM

I was a bit skeptical of this tuner, since a lot of them have huge promises, but I got a great price on it through AutoAnything and bought it. I have an Escalade with a 6.0 V-8 and RWD that usually gets 17.4 MPG on the highway at best on our road trips. I got as high as 18.9 and even through a 3,800 miles road trip driving on the highway, city traffic and up hills and mountains, it still averaged 17.3! The cost savings of using 87 octane plus getting better fuel economy were well worth it!

works great

Reviewed By William W (COLUMBUS, OH) Reviewed for a 2014 Chevy Silverado —6/27/2015 12:06 PM

I initially set the unit for 34" tires, the diameter of my Toyo ATIIs in 295 60r20, the speedometer was actually a couple mph over. After some downward-tweaking for tire inflation level, I setting the unit to correct for 32.75 inch tires got my speedometer accurate to within less than 0.5mph error compared to Garmin GPS. Keep in mind that actual tire diameter is dependent on how many psi you are running, so getting things right on the money may take some tweaking.
