I've been happily running a 3" exhaust, 36lb injectors, and 15g/19t hybrid for years now. With kids, smog, etc i've decided to revert back to stock.
So, it's wearing all stock sensors, stock injectors, lh2.2 engine management, stock exhaust system, and old 15g.
If i slowly lean into the throttle and bring it up to 7 psi (max stock boost with out an MBC), my AFR's do not richen up. Usually just stays at stoich or leans out a little to 15-16. Also kinda feels like it's bogging when in boost, almost as if timing is being pulled.
Any ideas?? What controls AFR when in boost???
I was under the impression that the MAF keeps it at stoich when not in boost, then the O2 sensor sees my exhaust leaning out when in boost, then richens the mix.
