Yeah, I don't think it is anything with the engine. Just giving Kevin some props, Kevin is an awesome guy and an awesome engine builder. It is something I goofed up more than likely. The PFC hasn't been tuned it is the stock (newer updated map). Fuel pressure is around 32 psi at idle. Boost line is connected to map sensor (but I will double check and make sure it isn't kinked or something. And they are the stock old injectors, cleaned and flow tested by witch hunter (all passed). Also It will not idle below about 1400 - 1500 rpms without stalling, idle is also really rough and once it warms up it does start hunting. Once it starts hunting, if I try to bring the idle down with the idle screw and air bleed screw to stop the hunting it dies. Smoking is also really bad, I pulled it out to drive on some back roads and couldn't even see the road behind me for smoke. Not sure if it makes a difference but I am also running premix 1:1 ratio (no omp). When I try to accelerate it starts cutting out around 4000 - 5000 rpms in any gear.
