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 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.
