FWIW mine also enriches under boost even if the WUR boost port is blocked off (7k rpm module). I had a thread on this here previously but never really worked out why.

Why does it still enrich?

I just presumed it was the fuel head and or pressures and left the rpm solenoid at 7k and I still see AFRs in the 10s on boost.

I have since replaced my injectors, BL rebuilt my WUR (leaky diaphram) and tuned her up to run really nice. Still enriches under boost with no boost to the WUR line!!!
