Huge difference in my 4.7 Grand cherokee...woke it up! this thing runs and gained 2 mpg in fuel economy. Only reason I rated ease of installation low was because I haD TO WASTE 15 mins updating it on my pc. for the amount of money I paid it should be pre updated. and its a bit pricey.

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.
