Default Part Priority Help!!

Hey guys, im relatively new to the site. and have been searching for how to figure out what part to buy next.
so far i have installed the denny t stage 2, BHAF/ cold air, and 3.2k rpm spring, along with pyro and boost gauges,pump turned up 1 turn, and star wheel maxed.

next on my list of things are things like turbo upgrades (compressor and exhaust on my H1C)
OR
Possibly an HX35 (found one on CL for 275)
which will supply more air without over doing it?

which would you guys suggest?
other plans include
sdx 5X14 injectors,
3pc manifold

Which order would you guys suggest i do these upgrades? and are there any others that you would suggest?
im looking to make my truck a powerful yet fuel efficient daily driver and toy hauler.
thanks so much
Sam

I would upgrade your turbo first, meaning get a bigger one, dont bother with building your H1C if you plan on running bigger sticks. Eventhough your truck is intercooled, it wasn't originally so it has the bigger 9mm injectors vs the 7's on the IC trucks. You can get a decent amount of fuel through the stockers for now. Once you get a bigger turbo then start looking into some 5x12 or 5x14's. The HX35 would be a decent upgrade and that is a good price if it is a good turbo. Valve springs would be good as you start pumping more boost.

ditto on the turbo might save some pennies and look for a used 62 and dont go huge on the injectors 5x.012's are plenty! might look into a lift pump or maybe just even a fuel pressure gauge to make sure you are keeping plenty of fuel to the VE i think 14psi is max.

What would the 62 be? hx35s are 57? what is the hx40 compressor size?
oh and what size would you guys suggest for the exhaust housing? 16cm?
