We are going to run wastegate pressure today. If we still encounter lean AFR's up top, the problem lies elsewhere. If it hits the target AFR's, it is most likely the fuel pump. I do not think the stuttering is being caused by the fuel pump, that could be blowout or possibly the fuel filter clogged up. But then again, I don't know.
