I'm running the AFC hack.

I have an inline pump and factory in tank.
DSM 450s.
-30 across board ( except idle )
Stock FPR

The car leans out during crusing and acceration, under boost and 55mph...

I've tried two different MAP sensors, added a new larger fuel filter, and still running lean...

 

10psi max.

I'm going by an A/F gauge, but the ECU has also thrown the code for running too lean, twice.

Its not only at WOT, even cruising...
