Smash in 2 bar. Done.

In all reality 'boost' is not the tune. 1 bar can be dangerous with the incorrect tune, so don't just go winding in boost without the fuel etc to compensate.

In all reality, once you start going past 1.5/6 bar you start to just blow hot air, so you don't get the most gains in power per psi boost your are upping it (if interested look at how the efficiency curves of the compressor map drop off significantly as you smash more boost in).
