UnderPowered M3...
I have just Dynoed my M3 in a very respected local Tuning Shop with years of expertise in BMW M engines.What i came across is a Pathetic 322 Whp with BMC Air Filter and Rear ACS Export Exhaust.The Dyno was in 4th gear....but i really dont get it...How come everyone in this forum have a average standart 330 + Whp Stock and me on the other hand have so much less...I could really use you comments here guys...Thank you in advance....
