His dyno tuner is afraid to push more power if meth added but I've seen more 550i's pushing more power and think he's playing it a little safe?
What is the maximum safe wheel HP number he could get on stock internals and what he would need to upgrade from here? HPFP? Meth? Pure turbos of course as well. Thanks in advance.

I think someone here did 700whp on pure stage 2 but as far I know no one has either found the limit or pushed it that far or we haven't had any one talk about it.
