Planning on top swapping my 02 GT. Right now now im looking at the Intense racing, overkill, or the 3800performance DHP tunes. The mods on the car would only be the top swap and headers, with the stock pulley on the supercharger. I looked into the DHP but that recomends a 3.4 pulley. Any thoughts? If i could though, id want to get a DHP tuner with a good base tune and try to learn tuning anyways.
