Agreed!
I'm not sure how much boost the stock manifold will take abuse on though. I've seen other blow them with relatively low boost (under 10PSI).
Mike at Maxpsi is working on a ECU tuned kit for the E46 M3, using the stock S54 manifold, and he will definitely let the community know what the limits of that design is!
Again guys, good luck and happy boosting!
