15g upgrade checklist?

[Hard AttacK]

I wanted to go single turbo, but nobody would help me do it or tune it....so I'm thinking I want a 15g setup with around 400 reliable awhp on my all stock longblock and heads. That will leave me with more power to be made down the road.

Here's what I know I need.

550 injectors
walbro or supra fuel pump
something to tune with (piggyback?)
Air/fuel gauge
quality boost gauge (my prosport sucks)
new oil feed lines
FMIC
Stage 3 clutch
T case brace
BOV

What else?? I know there's more

Thanks!
