Rev 3 turbo, standard turbo as far as I know with a Berk DP.

Running Blitz Dual SBC.

Also been running BOV-less for 6 months if that could affect the following:

Recently started hitting boost cut/fuel cut/some sort of wall at 1.15 bar on the Blitz readout.

Obviously this is irritating as it keeps hesitating under acceleration so I figured that if I just lower the gain a little bit then I'll be running less boost and all will be well.

It's worked great like this for months, having to occasionally adjust on colder days or when the conditions are damp but all in all pretty reliable method of maintaining a consistent boost pressure.

The last couple of weeks I've had to keep reducing the gain as it seems to be hitting this 1.15 bar wall quite often.

It used to run fine with the gain set at 60 but now I'm down at 54 and it's still flashing red, beeping and limiting power when on full boost.

Is this likely to be a vacuum leak? Could it be clutch slip? Or something more serious like the turbo disintegrating? Sorry if the description is a bit vague

- haven't really had issues in the last few years of ownership and so I've just left everything as it was and kept up with basic maintenance, avoided messing with any of the stuff I don't understand
