I'm jfd's freind. Anyways, to out 124 psi's of fuel under full boost does not sound right to me, unless I'm just not understanding exactly what you are saying. That sounds like way to much due to the fact that we set it at 60 Psi in thew rail and the car ran like s****. The 124psi you are talking about is in the fuel rail right??
edit: ditch the greddy box!!!!!!!!!
