At 7K to 9k it goes from 13.0 to 10.9. If I take any more global out it starts to run at 14s before 7k.
My fuel pressure is spot on at boost. It's an AEM AFPR.
It's a full blown double pumper. 255s
-8an feed to -6an return line, I can lower the FP down to 30 psi so I don't think the return line is too low.
I've lowered boost and FP to see if that helped, no.
Changed ECU, this is V3 ecm link setup.
I have tanked the SD table settings at that range with little help, it was around 96 and now it is 86.
I've leaned out the A/F est as much as the ecu can which is only 12.9.
I have played with deadtime all the way from 30 -225, these are bosch 2150s, no help.
It just feels like it can't bleed off enough fuel and it is fuel creeping.
I am open to any and all ideas.
