Side note: The gen 2 FIC +30's we used would not run LT4 rail pressure without misfiring. The gen 1's would however. You need 2900 psi for the LT4 hpfp.
I would do:
XDI +30
LPE HPFP pump
+42% cam lobe
This will allow you to run less rail pressure(2175psi), have plenty of fuel for E65, and the low side will extend out a bit further and you might not need any additional low side upgrades aside from the LT4/JMS combo up to 13-14psi of boost.

Ok im going to be honest and already got the 32% cam and FIC 30s. Had no idea about the missfire and thought the FICs was the better option. But will getting the LPE hpfp Pump at least help lower the railpressure then? Thanks for the info.
