Is it a M6 or A4 car? Even for a M6 thats alot for those mods. Im not sayin it aint possible but basically your sayin that your heads/cam choice alone netted you like a 100HP gain no special tricks included...IDK. And 20+HP from opening some cutouts sounds like alot too. I say try another dyno that does mainly mustangs/F-bods etc. Thats why i always vid my dyno sessions too. Ill hold the verdict for some charts tho!
