I just got mine sharked and I have no clue. I also dyoned the car before I sharked it and apparently it had 250hp when it was 100%stock. I heard a lot of other ///MZ3 owners say the same. I think it is attributed to the Quad exhaust setup, that gives an extra 10hp than the stock ///M3. I could be wrong, but I swear that my stock ///M had 250hp showing on the Dyno. I hope this does not start any flame wars. Just wanted to know what you guys thought. Thanks.
