Do you know if BMW has ever released an engine upgrade during their M3 model run(s)? I'm not talking about a CSL release, but stock only.
I thought their engines pretty much stayed the same the entire time of their cycle.
I keep hearing that several aftermarket ECU upgrades easily get you an extra 10 to 15 increase in both hp and torque. You would think BMW would at least do that - or offer it under their performance parts line. That along with the multi-piston brake calipers that are stock on the 135i sport!.
