Need Help Picking A Wastegate Actuator

[SLC87]

Hey guys,
I am going forward with my X turbo swap much sooner than I planned.
I got a really good deal on a basically new X turbo and everything else I need but I noticed it doesnt have a wastegate actuator.

Normally I would just buy a stock X WGA but I am upgrading so I would like to get your opinions on my options. I have no idea how adequate the stock WGA is. Here is the setup I will be running.

OEM EVO X Turbo, Manifold
3" Widemouth Downpipe
3" Testpipe and 3" Catback
EMS Intercooler Kit
Cobb 3 Port EBC
And of course a custom tune right after install.

I may have an SSP clutch kit for the SST put in early next year, at that point I will probably step up my injectors and fuel pump.

Not sure if OEM WGA will be adequate or if I should go aftermarket. Spending $30 for a low mileage takeoff versus $150+ for an aftermarket one sounds nice but only if there isnt much of a tradeoff.
If Aftermarket, what PSI WGA do you guys recommend?
