Like it says. I have an 01 Z28 thats been modded out. Cam headers intake stall nitrous suspension etc. At first I was only concerned about goin fast, but now I have a car that is way too loud, gets dismal gas mileage, and still has a crappy 10 bolt rear. So Im thinkin of upgrading to an 03 Cobra. With just full exhaust and pulley I could be gettin up closer to 500 rwhp with much more daily driveability than my sub 400 rwhp LS1. So I was wondering what kinda gas mileage a slightly modded one gets?

No Pulley, but 400+hp at wheels and I get 15mpg city, 18mpg avg, and about 21mpg hwy. Pulley change is in the works.
