Well, my first setup was Blow Thru with GM MAS and MAFT and the AFRs were around 12.5 in between shifts. Now I went with recirculated setup with the GM MAS before the turbo, all hoses and line connected correctly and the AFRs are way off now, in the 10.0s.
Why is that? What can I do to fix it?
Car shuts off after being in boost or sometimes even randomly due to very rich conditions. It never did this before. It used to run very solid
Cruise and Idle are around 14.7, WOT at 11.0, in between shifts it varies from the amount of boost I guess. It goes from 13.0s at light throttle to 10.0s at 10 psi.
BEfore with the Blow-Thru setup it looked like a spike for a second and now it actually holds it for a bit which causes my next gear to be very slow.
Boosts to 10 psi with no problem, Vacuum at 22 inches
MODS: b16g, FMIC, AFPR, 1g BOV, MAFT+SAFC, Evo3 O2 housing, SBR manifold, 1g TB, 2'' IC pipes, 2.5'' UICP, 3'' turbo back, High Flow cat
Oh and now my engine sounds like a hair dryer when turbo is spooling and i can barely hear the BOV.
I wasted the whole day today welding the pipes and now it seems like i might have to undo all of it.
