I would like to find someone in the central PA area that's capable of "properly" setting the timing on my 7.3 IDI. I had the heads rebuilt, and added a new injection pump & injectors. The garage set the timing by ear. The power is terrible and the fuel mileage is worst than before the parts were added. It's also very difficult to start. I'm sick of it and ready to pay someone with knowledge of these engines to make the proper adjustments. Does anyone have specific knowledge of a garage or individual capable of doing this in the central PA area?
