Just FYI, the fuel pressure didnt drop that much at first when it started going lean, maybe 2 psi. Then they gradually die. Didn't go out all at once. Eventually the car fell on its face at 4000 rpm like a spark plug going bad.
Just part of hot rodding.Glad I use 100% methanol injection. Word to the wise it is excellent insurance.

It was the pump.On my last check with a fuel pressure gauge the pressure became more and more erratic until it just lost power after 4000 rpms. It ran like normal for more than a week out of boost until it crapped out.
The BAP was ok. Voltage was 17.2 when running with hobbs bypassed.

Boost a pumps are just a bandaid to make these kits work with a simple installation. I would recommend upgrading your fuel system, I happened to have a racetronix dual pump setup with wiring harness all new in box
