Most of my driving is city, I averaged 15mpg before then with the mileage cs save tune I now average 17.5mpg. Truck ran high 17s in STOCK setting, I have aftermarket exhaust, headers, and air intake. With performance tune I run high 15s. I can tell a great difference in each tune with shift points and firmness...great product!
