Thanks for the detailed report Les.
I can sit here and guess all day about what your issue could be. I don't really see "defueling" in your graph, more like a ceiling.
Ultimately, you're probably a little short on air, and a bit short on high pressure fuel.
I couldn't manage any better than 605 on the stock pump. Bolted on II's pump and was at 659. A little more air and was up around 690-- all with the same injectors.
The only thing that makes me think something is limiting your fueling is the fact that you're making the same power on all levels that you tried. With a stock CP3 and 90 hp injectors, you would likely be making less hp on level 8 than level 7. When I ran SW5,7,9, there was about 15hp between each level.
Anyway, thanks for a meaningful post in the middle of bunch of useless rambling.

JP...I am very curious to see what a good Cp3 can do for me.
I get the fact that I am probably out of fuel, but what boggles my mind is the draining the rail UNTIL peak power is achieved then it spikes up to 25K and holds steady until the run is over....if I am supposed to be fully fueled till 3500rpm's, or 4K wouldnt RP continue to be at the 21-22k level????:bang
The rapid increase in RP after peak power indicates that fuel/duration is being pulled...allowing the rail to become full again and maintain 25K.:what:
