mmmm...scary to run both Juice and a blower...
How much boost and juice at the same time?
Could be that you will need a bit larger injectors, depends on the total HP output.
Whats your HP estimate, and from that go one step larger.
Say 400 hp, then you need 36lb but for safety go for 42s to reduce the duty cycle. And use a big pump, 190lph minimum.
Dont use a FMU, better to have a dual program chip with 2 programs one for PSI only and another for PSI+Juice.
Install and adjustable FPR for fine tunning.
Select the right plugs, very important, you dont want stockers in there, go 1 step for regular use or 2 steps colder with both juise and boost.
