How will this do? Should I go with the LPE pump instead and dsx aux also?
Goal would be going e65.

Depends on boost level and power it's trying to make. My guess is that setup should handle E65 up to 750-760whp before the low side starts to reach it's limits.
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.
