Depending on how many kms are on your motor you might want to walnut blast the valves first before running meth, but the Meth will really help get you to 400 Whp. iv read that you can get 400whp on a n54 135i with just the JB4.
As for the n55 between the E series and the F series, i believe that there isnt much of a change between the two, however the aftermarket and tuning availability for the F series is very limited at the moment so you cant really do much.
Again this is from what i read and understand, so just keep reading.

Because I been reading on n55 f30s and there is a couple already actually on just e85 and 91 mix and FBO
