370z vs 335i Coupe

Some of these numbers seem amiss. The "lowest" boost setting makes 360 whp? It's rated at 300 bhp, so I'm thinking 260 whp stock? So you're saying that just by turning up the boost you're gaining 100 whp? I doubt this, but if so, what is the stock boost? And what boost is the "high" setting? 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

8 psi is stock boost. 360rwhp is far-fetched from tune only. See my post above. Now don't get me wrong, at 15-18psi you can easily be 350-390rwhp, but without any supporting mods you're raggin on the engine.

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.

Agreed...I was running 93 octane at about 14.5 psi. On my 135i they dyno at 340whp with 91 and map 1 on JB4.

I have a meth injection in the mail
