-alright I'm running 65% WGD and 14psi (compared to 17psi) through most of the power band. just started having rear 02 sensor CEL come on could this be my problem? or should i pull the stethoscope out and listen for knock? no other CEL's expt for secondary air injection which is smog pump and i am not worried about that. have been running this bad rear 02 for a month which i did not think made a diff cuz cobb ap is supposed to delete the cel for this cuz the wack reading w/a catless dp? or do i have no clue what i am talking about lmk thanks.
-is this higher humidity/heat making ecu cut boost to prevent pre-detonation? when it was 60 degrees or less out i was running easy 17psi not sure what the WGD was didn't log and building 10psi b4 launch. then as the average heat out here is now about 70-90 degrees w/ humidity upwards of 95%to 100% boost dropped to 14psi.
-haven't heard any noises other than normal tgv tic.
-02 sensor was bad still running 17psi did not psi drop till LC/FFS map update. went back to reg stage 2 no /LC+FFS still same 14psi.
-can make data logg if needed lmk thanks
