Well i was wondering if there are any SAFE ways to go over 10psi without going to a full satnd alone like the power fc?

Pettit ECU, M2 ECU, PFS Purple...

I have ran 14 psi on both the Pettit and the PFS.

What is the PFS Purple? Is that a reflash like the Pettit and M2? I'm going to have my ecu sent in soon for the reflash not sure if i want M2 or pettit.

M2 is gone (as far as aftermarket parts sales). You'll have to find used one if that's what you want.

PFS Puple is a piggy-back ECU. It doesn't replace the stock ECU.

You can go up to 12psi on the stock ECU before fuel cut occurs (@12.1psi roughly). You're A/F ratio should be fine up to this point. However, if you have a boost spike above 12.1psi, the results could be terminal. Best advice is either get a remapped ECU or a standalone. Don't push the envelope.

Nope. The stock ecu enacts fuel cut at 10.7 psi at higher rpm.

Just get a used Pettit ecu for ~$400 and be done with it.

Fuel cut varies depending what RPM you are at

RPM----SEA LEVEL CUT OFF(PSI)

1000---11.8
1500---11.8
2000---11.8
2500---11.8
3000---12.2
3500---12.4
4000---12.8
4500---13.3
5000---12.2
5500---11.3
6000---11.1
6500---10.7
7000---10.7

Thanks, was too lazy to dig up the chart....

All of those values are for sea level. He's not at sea level

~10psi with a stock motor and stock twins is very much different from ~10psi with a mildly ported motor and a bigger single turbo.
