im very sure it will deliver the results mate, but i do think if you go on track or drive very hard on the road it will go into limp home mode with that power through a tuning box. Tuning boxes up the fuel pressure via the fuel rail, the ECU in turn senses more go go juice and then ups the boost. Not a brilliant way of tuning but it will give good HP gains. Reliability of injectors and fuel pump may be an issue after many miles.

Try one and let us know what you think. They have a money back garuntee if you are not happy.

M3 gone .... But I now have a M3 CS

Based on this statement;

The additional P-Tronic units allow engine's power and torque increase while reducing its fuel consumption.
I wouldn't touch one with a shitty stick.
