I have a procharger with magnaflow exhaust system (503 RWHP)and stock 2.72's for now. It's a blast but looking into the 3.73's. I think 3.90 and 4.10 are just a bit too much. I drive my car everyday (19,000 miles) and like too get on it from light to light. I think these are the gears for me.

The effective ratio change is due to a smaller circumference on the 305/30's compaired to the 295/35's.
