Hey man this post was about 5 years ago but I’m having the same issue and I see you mentioned AFR. My Sr20det was running perfect with an intake stock (maf) untill I installed a Greddy intercooler ,my car wouldn’t rev past 4K I don’t have gauges or any idea of my afr
at the moment. But obviously my car has to be running more lean. Does that have anything to do.
