Somthings wrong with my turbo/engine?

[yzfsr20]

I'm not exactly sure but after a night at the drag strip my turbo won't spool up right. the engine and everything else seems fine, no smoke anywhere.

but my psi won't build. now that sounds like a leak except for my a/f is all fucked up. it will get real high 16's 17's and backfiring.

What should stock fuel pressure be? I'm going to check that first

I would check your connections for all your piping (intercooler etc). Especially any rubber connections, then the MAF. Sounds like a boost leak to me

Definitely sounds like a boost leak to me too, Do you hear any compressor surge action at all or what?
