Here is a bit of "learned" advice - The AVO DP does not hook in directly to stock pipes. If you HAVE to have the DP - then get a total turbo back set up. But like Acumenhokie said, a DP is really not needed until you wanna start throwing bigger turbos (dumb idea
) on the car.
Great gains can be pulled from an upgraded TMIC and really a CBE....
