370z vs 335i Coupe

If you're gaining 100 whp that has to be a difference of almost 50% boost or more, which in every other stock turbo car I've seen, would need bigger injectors, fuel pump, oil cooler, and FMIC to operate without heat soak, knock (there must be a timing advance in this tune - there's no way it's just from increased boost), etc

For example, in Houston I dynoed stock at 282, after tune I was in the 330 range at 12psi. After I installed my dp's, fmic, exhaust I was around 380-390. Then w/ meth I can jump above 400rwhp on pump 93.
