Well you have to remember my baseline was 310~whp On this Dyno. I'm not calculating the number as a loss but just how the Dyno reads. Every stock M3 i've see has dynoed 303-318 stock on this dyno. Most people calculate 17-25% on a Dynojet or Dynapack where stock M3s dyno at around 335-350whp. If I were to dyno on a Dynapack/Dynojet I would probably get around 485-490 easily.So this dyno is just to show the gain from stock which you can basically add to whatever Baseline you feel like.
