Trying to figure if a turbo would yield the same gas mileage as DOD. I have always heard that turbocharging yields a small MPG increase, so if you could achieve more power and retain the same MPG, it would be worth it.

Since we cannot go FI and still retain the DOD, what kind of mileage do you think we would be looking at?

2008 Silverado 1500 ext cab short bed
gen 4 5.3/4L60E
innercooled MP76
Probably a late model Z06 cam, since the cam/lifters must be changed anyway.

Averaging 16.5-17mpg right now, mixture of city/highway.
