how much can you pick up with a tuner?

I picked up damn near 40whp with my speed3 accessport and CAI

About the same...I haven't done a dyno since I installed the accessport. Just judging by others dyno sessions. Most eb make around 310rw once you do a tune, then get into the 340 to 350rw range once you do intercooler, downpipe and cai.
