Maximize 09 wrx turbo, next steps?

So the TMIC is done and so is the downpipe.

I've finally decided on my current goal is to maximize the output
I can get from the stock 09 WRX turbo.

The downpipe/tmic had done well to improve power but also increased
the boost taper effect at 5000+rpm. I would like to remove some of this
boost tapering and get the most out of the stock turbo without pushing
the turbo beyond its safe limits.

The things to achieve this are for sure a fuel pump upgrade. I have had
mixed opinions on injectors so I would like more input on this. For instance
if I should upgrade injectors, what size do I get? Can anyone post/email
me links to a vendor I can pick these up from?

This leads me to a question regarding the boost control solenoid. If I do
injectors + fuel pump, do I require a new EBSC?

My protune date is coming up and I am hoping to get the rest of these
mods done so I can have just a single protune to get the most out of
my turbo since this is how it will remain for a while.

tnx
