How does a tune affect the ls engines with the active fuel management?
I am thinking about putting a 5.3 in my 86 cutlass w/3:23- any ideas on what type of gas gas mileage I should see?

You can leave it alone in the tune--shouldn't be a problem. A 5.3L in a light car like that with a good tune should yield 18-19 in the city/24 hwy. But then again, it all is dependent on how far your foot is stuck in the go-pedal...
thx. Do u think the 5.3 or the 6.0 would be the better choice?
