I just swapped in a 4d56t into a Montero and it is running good but...I performed the injection pump mod (removed spacer from plunger and cranked wheel in pump slightly) and regardless what I set the boost at with the manual boost controller it seems I am not getting any change in fuel. No matter how much I turn the wheel in the pump, so whether I am boosting 9 psi or 23psi the power output seems about the same. I haven't touched timing at all yet. IDEAS???
