the fact that you have no clue how tuning works or what you are doing is a pretty clear indication that you should NOT be attempting to modify your car.

stop looking at parts, start learning and reading.

you have a LONG way to go.

Your turbo should be safe, engine, not so much. Stock safe boost levels are around 21psi mid-end and 14psi up top. You should be fine as long as you don't disconnect battery often. Let ECU retard your timing, fueling should be on the safe side stock. But if you're going to use boost controller, you should set it max to 14psi as it only allows you to have flat boost curve.

Horrible advice.

The fact that he didn't specify if he was talking an Electronic or Manual scares me. You don't just "turn up boost" on a car. If you buy an electronic boost control solenoid you NEED a tune, and to use a manual for anything more then keeping the current peak boost you need a tune.

Plus this is Interior/Exterior discussion, nothing to do with boost or boost control.
