i ,m having issues with running to rich 9.5 to 1 . I have turned to fuel pressure down to 31 psi and have a gotten it to 11.5 to 1 but now i have idle and hard starting issue , suspect the not getting a good spray pattern at the lower psi level and bottom end is lean i have 33#injectors in that came from an 89 2.5 CB would 27# injectors be better and running a slightly higher fuel pressure ?
specs
2.5 CB tO3 turbo 33# injectors
MP log IC
stock t2 cam
MP 85 logic module 13psi
timing at 10*
185* thermostat
autometer wide band mounted 5" down stream from turbo
3" turbo back exhaust no leaks
no cat
also note that when i get to temp it starts to richen up the fuel even more at cruise
