I've had alot of problems with my boost dropping out at higher rpm's and i've been reading different things and I decided to unplug the MAF. This helped alot as the turbo spools up quicker and it holds longer in the higher rpm's (still drops down to 5 psi abruptly) but now the MIL light came on (not flashing) and not the CEl which I was expecting reading all the previous posts. Is there something I should be worried about?

Re: Unplugged MAF and got a MIL not a CEL (RQuinn19)

If you unplug the MAF, you should get a MIL(engine looking icon).
If you are dropping down to 5psi in the higher rpm, it sounds like limp mode.

Thanks but why would me unplugging it delay the limp mode?
My main problem is that at the track I've run a 14.41 at 92 and I think the reason for such a low trap is that right at the end I hit limp and it feels like I put on the brakes.

MIL and CEL are the same thing. People refer to the Malfunction Indicator Light as a Check Engine Light all the time.
Just a guess but with your GIAC chip, MBC, and H N75 you are overboosting like crazy. So when you exceed spec boost your car closes the throttle body and reduces boost.
