Can't find my fueling problem only place left to go, besides upgrading CP3. Yes, checked filters, fuel reg., lines and lift pump. Shim mod this week.

What is your "fuel problem"? Is your rail pressure dropping? What PSI do you have on the feed line to your CP3? Or have you looked at your PSI that your lift pumps are putting out at idel and WOT?
