My only question is, the "before-tune" figure was under 150rwkw, 147rwkw I think. Would this be a little low considering that the mods were already there?
Maybe something to do with the dyno to generate a lower initial figure? Not 100% sure. When I first dynoed my car in "almost" stock form, it came up with 159rwkw... so it seems a little low. The current setup is getting me 194.6rwkw - maybe his final figure isn't the question, but the intial figure?
