Stock STI (C&D): 0-60 4.9sec 1/4 mile 13.4 @ 102mph
Stock 335i (C&D): 0-60 4.9sec 1/4 mile 13.6 @ 105mph
I think the ET on the 335i gets inflated a bit because third gear tops out at 104mph apparently...
So it looks like, based on trap speeds, the stock 335i should pull on a stock STI, but I really don't know how much faster stage II makes the STI - I thought it was quite a bit?
I know guys are flashing the 335 with intakes and DP and getting some big gains though, many say that just a flashed 335 will toast an E46 M3 (in a straight line at least)
