Fuel mileage??

[stoopstroop]

I have a 2006 silverado 5.3 Z71 crew cab. What can i expect to see my average fuel millage differ with the 87 tune? And is this guaranteed?

Thanks, Stoops

We can make no guarantees about fuel mileage as it differs quite a bit from one truck to the next. Driving style, vehicle setup(4 wheel drive, gear ratio, tire size) and a host of other factors determine what your mileage will be.

Either way, as long as your driving style stays the same before and after the tune, there is no reason you will not see some gain in the mileage.

Thanks
