Finally pulled my plugs, all black. Sure doesn't look like fuel starvation now. Gave em a good cleaning and reinstalled. Car is still the same low on power. Did a diagnostic of the MFI pump thermostat and it is working perfect. Checked the cold start prime and no leakage. Next plan to do a fuel pressure test and looking for other suggestions.

Other info:
Almost everything has been replaced. New injectors, fuel filter, all soft fuel lines. MFI pump has been cleaned and inspected by a local diesel shop. Electric pump is original.
Wrench who did the final tuning on the car indicated he had trouble adjusting the pump. He pulled the adjuster screw and said there was some evidence of grit in the pump. What are my next steps?

Thanks, a frustrated MFI guy who had a taste of how good it can be.
