Just wanted to offer an update on an Autocal I installed in my bosses bone stock 2006 LBZ. Truck has 70,000 miles on it and is 100% stock, right down to the paper filter and factory brand tire and size. Running the 80hp tune and nothing else, truck gained just over 2mpg daily driving (hand calculated).

Boss is super happy. Thanks DmaxTuner
