mean your engine will want more fuel then the stock injectors can provide. why you would need the 42's and be tuned for them.
on the other hand, dhp tuners are cheap and if your gonna do a ic and all, may as well put a tuner in your mod list. canned tunes work ok, but when you can fine tune it to the cars needs its so much better.
forgot your a GEN 5 blower, a 3.3 might be better then a 3.2, but you'll still be maxing out them stock injectors.
