What the heck is an injector seal? Don't ever listen to the person that said that again.

Open exhausts can overwhelm stock internal wastegates, which leads to boost creep and potentially blown engines.

so what route do you think i should go?

For what? Read through the 2nd gen section to get familiar with common modifications made to TIIs.

what do you think of FCDs?

I don't think much of them. They alter the boost signal to the ECU to get around fuel cut, but that also means fuel and timing are negatively affected. Chipped ECUs from pocketlogger.com (Rtek 1.5, 1.7, 1.8, 2.0+) are much better. What are your plans? Do you just want to be able to safely run more boost on the stock turbo?

for now but basically want to bore out the stock turbos waste gate and rebuild it then i can run more boost with out boost creep i dont want more then 300 hp pretty much
