I have DSX Flex Fuel Kit but will hold off until this coming fall and send my ZL1 to get a stage 3 or stage 4

You should be able to run between E40 and E50 with a JMS booster. Most of the mods you have done are adding very little gains at your current power level. The headers and cai are the only 2 really gaining you anything.
