Fuel cut is supposed to be at 15.5 PSI and no earlier.
The injectors are supposed to work fine until you upgrade to a 18T turbo.

The 15G turbo's are also known to have bad boost fade.

When I run my chipped ECU it was kind of doing the same thing. I kept forgetting to bring home all the proper tools from work to look at it on the weekend so I took the ECU out till I can perform all tests on it.

Currently the wife is running it in her car with no problems at all.

OK, I will put the T5-R ECU back and do a leak test or so...

Thanks !!
