Need Help Choosing Injectors for 2.4 Turbo Wrangler

I hope this is advanced jeep tech enough...

I was following a few thread on turbo 2.4's such as Air Sierra's, CrisSmith..'s etc. but they were only pushing 6 psi of boost. Air Sierra's worked without any Fuel management or computer changes. Air Sierra stated that the stock computer was able to compensate up to 10-12psi of boost. I am going to attempt that 10-12 psi of boost. I'm doing a front mount air/air intercooler and flipping turbo upwards like Air Sierra.

My question is... what size injectors (at stock 49psi) do I need for the 10-12psi intended? Air sierra used 27lb injectors but only boosted to 6psi. Part number he used was 1W7EAA from fiveomotorsports.com

I appreciate any and all help. No bashing on the poor little 2.4, please. I am eventually doing an LS swap but want to make due with what I have for now, so again, no comments on that, please. Thank you.

If it matters... I will be in altitudes ranging from -50 to 50 feet sea level.

Again, thank you.

Can the stock fuel pump handle the additional delivery requirements?

I bought it but haven't installed it, I may need to make spacers to push radiator back a bit. Waiting on correct injector size to go ahead with install.
