Depends on your boost level. More specifically crank horsepower. If your fuel setup can handle it, then all you have to do is have the chip properly programmed. I would assume Fast Chip could do that, but I haven't looked into it. Dyno Tuning is always an option.

YTour going to need something as your ECM does need boost. You may be able ot do it through a custom chip under power enrichment. Your car is not like a MAF car which can get away with a little boost because it reads air flow.
