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!

Better than Bully Dog

Reviewed By Jonathan W (Killeen, TX) Reviewed for a 2015 Chevy Silverado —6/21/2016 4:47 AM

I had bully dog before this one and it took me and my truck through the ringers. This product I should have stuck with since my first use in 2004. I love this product and will recommend to anyone.

Worked well!

Reviewed By Shane P (MOORE, OK) Reviewed for a 2015 Chevy Silverado —6/10/2016 4:39 PM

Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.
