e30

i get 30ff at 6500 rpm every time in third gear with the 91 octane map but only a few weeks ago had a smoke test and fixed any boost leaks at a bmw mechanic shop. and there is a hard dip in rail pressure with the e30 map but only at 4500 rpm I assume it is because the rpm is not high enough for the hpfp to create adequate pressure since at 5.5k+ rpm the pressure is around 2000 psi.

Outside temp 21C.
