I currently have the mods in my sig and am in the market for a CAI/RAI and possibly UD pulleys. I know there are a couple of levels of Trans upgrades, but don't quite understand what each entails. Eventually this will be a S/C car for the street, with the occasional 1320 pass, and I am trying to plan how to get there. Can someone give me the "Upgrades for Dummies" version of each level with approximate cost and what is required for 400-425 rwhp?
