Yeah I agree with you on the black box causing the issue bc I don't know exactly what it is. I was using a no name rrfpr for a while but wasn't sure if it was also causing problems so i removed it. So if I remove the clamp from the map sensor I should go with the gm 2 bar map sensor? It throws a CEL when I disconnect it. I think I read something about scaling the map sensor?

For now I have stock injectors with a walbro 255 in tank pump. I need to find some wrx 440's but I think the 251 I'm gonna install has the air injection issue with the injectors. It is out of an 02 legacy. I have to pull the injectors tomorrow to see for sure. If that's the case then I have to find a different intake manifold for the 251 to accept the 440's unless the intake on my 2.2 will fit....
