Thanks BB 2 stroke. Question, does the ECM base fuel injection timing events solely off the crank sensor signal? If so then this mod will do something. If it used a combination of signals (say crank + cam position) then we may be hurting more than helping because we are introducing error into the eqaution (difference between the crank and cam sensor positions).
Any thoughts?

Thats MR Hoss to you buddy!
I think he already said he didn't know the answer to that question.
The simple answer is that if your truck runs worse or drops in fuel mileage then you have gone too far.
