Tuning question

[Catnip]

My car is running rich up top under boost, so the question is, do I keep making negative corrections to the SAFC (doesn't this also retard the timing?), or lower the fuel pressure? The AFR under boost with 0 corrections is about 10.0-10.3 while cruising the AFR is 15.3-15.6


Air/fuel mods:
680 PTE's
2g maf
afpr (set at 42ish PSI)
aem wideband
safc2
dsmchip stage 3 chip (set for 680cc injectors and 2g maf)
logger (SOON)

thanks for all the help!

just pull fuel with the SAFC, if it pings, 0 it back out and make a gross adjustment w/ fuel pressure and then fine tune with the SAFC.

SAFC is not retarding the timing. Just pull fuel under boost. Your cruising AF is good/little lean.
