Not intended as a flame - curious... Coming from VAG world where modern VeeDubs easily add 50hp/l in "Stage 2" tune, why is the bimmer tunes so feeble? I plan on ED next spring on a 6MT M2, but was hoping for power increases like I'm used to. Thoughts?

BMW tunes are for from 'feeble' in most cases. It just happens that the M2 lump is already a tuned version of the M235i lump, so gains aren't as good as the M235i, M2, 135i, M6, M5, M4 etc etc.

well, being new to these forums, how about pointing me to where this has already been covered? For instance, a stock golf R makes 146hp/L. at that same efficiency, the M2 should make 438hp just to start with. The R can get another 100hp in stage II tune, where the M2 won't get anywhere near that HP/L (not even mentioning the AMG 2.0l 4). Did some googling but haven't seen anything that delivers that kind of efficiency/l displacement for BMW. Is BMW just behind the game on engine design these days, or is the VAG stuff just that good? Won't impact my Germany trip and purchase next summer, but would be nice to see more bang for the buck in chip tuning the M2... who's best so far?

BMW isn't far from those numbers now. They don't have a 4-cylinder high performance application yet. They do have a 6-cylinder high performance application called the S55 which already does over 438hp in the M3/M4. Been out for a while??
The M2's N55 could do the same and much more with tune and larger turbo. You need to continue your googling.

It took years for the 2JZ to reach its full potential
