a stage 2 Technique Tuning kit, with a full 3" exhaust can make close to, if not right at, 400whp and more importantly, unlike supercharger kits, you're going to also be pretty close to 400wtq, which is even higher than Max PSI's new m3 turbo kit can produce. if you can be happy with 350-400, then go ahead and boost the m54, if you think you'll ever want more than that, get the s54.
