Saw some interesting stuff at the dyno day at 22RPD.
There were two M2 Comps - bone stock did 427hp!!
different M2 Comp had beautiful Eventuri CAI and did
less than stock one, 420hp I think.
M4CS stock did 454hp.
black E92 M3 with a monster supercharger (didn't get the brand) did 505hp.
My E92 M3 with Dinan CAI, test pipes and BPM Sport Stage 2 only did 350hp.
Rod bearings done; DCT tune done on the 3.62 diff; Liquimoly 10w-60 oil change, etc. all service good.
I've emailed Mike, something is not right. No issues with the car on the street, but the dyno numbers from Stage 1 and 2 tunes are way off.
