As title states i am getting a average idle of 16.7 up to 18. Same with cruising is average 17.1. Seems to be fine when going wot. I have been fixing stuff on this car since i got it and this is about the last one! Got the ignition timing dead on 20deg as i am a auto. Some info on the car is a 1991 cefiro with a rb25det. Running a holset hx35, full 3 in exhaust, front mount intercooler, knock off greddy intake as i cant find any stamps, gtr 550cc injectors, blitz bov, tuned with rs enthalpy. Again all of this was done by previous owner and this may be something as simple as a new tune. Replaced plugs and gapped but didnt change anything. Verified fuel pressure at 2.8 bar (roughly 43psi) with the vac unplugged to the fpr.
