I would also have in mind crappy injector O-rings or injectors that are bleeding off HP oil pressure as well.

I was wondering if that might be my problem? I'm not seeing any smoke, my truck runs normal, but my pressure is not up. I'm seeing the same thing the OP is?

If the injector O-rings have never been changed I would certainly consider that as they do tend to die with long use. The guys from Swamps or one of the other injector shops could probably also give you some ideas on if it is getting time for an injector rebuild given your mileage/use/maintinance.

When you were testing was that with the chip in the hottest setting and with the truck at WOT at say 3000RPM. What was the pressure and the duty cycle?

It about the same in any tune. Most icp i have ever seen is about 2000-2100psi. Duty cycle stays less then 40-45% at WOT. Icp voltage gets up to about 2.66 volts at 2000 psi. Fuel injector pulse width gets up to almost 5ms. Is that normal? I can email some data logs if you want.

Interesting but glad you kinda layed out that you really do not have a mechanical issue.
