As far as anyone who questions our ability to supercharge BMW's correctly simply visit our website esstuning.com and look at the number of BMW's we make superchargers system for. With 14 years of proven expierence tuning and supercharging BMW's I would say we know a few things about how to properly build and tune kits
Our current stage 2 E90 M3 supercharger only requires 5.5 psi to make 518 whp and our entry level stage 1 non IC kit makes 470 whp on 4.5 psi. You simply cannot make this kind of power on this low of boost unless you know how to design and tune supercharger systems properly.
I'm sure you do know how to tune you're cars but anyone can make the same power you did if they are running the same blower, it has to do with how efficient the blower is rather then the psi. 5.5psi from a small blower is alot different the 5.5psi from a larger blower.
