Currently I have a 01 with Hedman Headders, Dual Flowmaster 40's, K&N FIPK filter, and diablo tuner. At the end of the month I am putting 3.73 with a T-lock, And after that I am looking for a power adder and came upon the M90 Supercharger for the 3.8 and was wondering if it would be worth it or go another route, I was going to go with the m112 but that's alot of work to do and also having to buy a new hood and i saw the M90 and looked fairly simple so any ideas or suggestion ppl
