Stage 2 E30 ----- 392whp, 442wtq
Stage 2+ E30 ---- 415whp, 466wtq
dyno map shows stage 2 E30 held the power to redline, but there was a massive drop off in power for stage 2+ after 6k rpm, so basically with the stage 2+ tune, shifting should be done at or around 6k rpm...
the Garage was super hot (over 100F) when I did the dyno, and car was running stock bosch plugs at 0.022 gap, a little disappointed with the numbers honestly, would liked to have gotten maybe +10 whp more on both maps, but oh well.

turbo is done on a stage 1 tune at 6-6200, it's just can't flow the air efficiently enough to make boost. it's too small.
