e30

I think I have a boost leak

E30 mix, dp, B58tu pump, and jb4 w/bef race gas map

1 step colder plugs gapped between 22-24 thousandths. All checks OK(no shadow codes either), oil at temp and full. DSC fully disabled. Valve cover leak, PCV hose broke. Sport mode to manual mode, 3rd-4th gear pull. Battery under 12V when Car off, fuel rail pressure fast decrease. Suspect new battery and fuel pressure regulator needed.

Some E. Breaking up at redline

e30 stage 2 - just checking rail pressure and AFR

LTFT high until I get into boost
