2G Fuel cut problem

I’m experiencing fuel cut at about 11 PSI. Anyway to combat this? Could an aftermarket fuel pressure regulator fix this? I’m sorta stumped on why the ECU is doing this..... any help is appreciated..

Thanks

have you done a blt?
Is there a boost controller on the car?
Check to see if the wastegate actuator is working properly also.

Also check for boost leaks. At that psi you shouldnt be hitting fuel cut.

Perhaps the plugs are fouled? Fuel can and misfires can feel similar.

I haven’t done a boost leak test yet... that’s something I need to go ahead and buy (a tester).

I’ve taken boost controller off that was installed when I got the car. It’s hooked up to stock wastegate pressure.

I’ve noticed that when I first start driving in the morning when it’s cold, it shoots up to about 11-12 psi and hits fuel cut. Then after it warms up shoots to about 8-9 psi and then immediately bumps down to about 6 psi....
