OK, all good input.
I am now thinking about using the 240 injectors with the rising rate FPR. Just lowering the base pressure (I'll test the spray patterns).
As for the WOT comment, I am not sure it's true. WOT has nothing to do with boost. The superchargers that Frank & I are using are similar, as in that they both have a bypass valve located in them. The valve is vacuum operated from the throttle body to open up under high vacuum operating conditions (idle, cruise) & close during low vacuum conditions (acceleration & WOT).
I personally think that with the bigger injectors with lower base pressure & a rising rate FPR, I should be able to keep within the ECU parameters. The manufacturers of rising rate FPR's are pretty savvy to boost applications & can tune them to work right. I will find out if they are a linear rate of rise & report back...

Thanks for all of the input...
