Was it an auto before or still a T5? I can't imagine a T5 robbing power on the dyno as long as it went into gear and moved the tires at all. If it was a T5 and you just put a new one in, you probably won't see a noticable increase in power. The cold air kit won't do much on the dyno, underdrive pulleys may be worth 5hp, and FPR won't do much unless the air/fuel is off which it shouldn't with those basic mods. Its getting nasty out weather wise, so if you dyno'd in the winter before, you may see a loss of HP, but any gains will be minimal I think.
