Is it ok to turn up boost with the stock uppipe in place?

I have a turbo back exhaust, airbox silencer removed, and samco hoses. I still have the stock uppipe in place. Is it ok to turn up the boost with the stock uppipe?

If you have a stock turbo, no. Not really worth it when you weigh safety against the gains.

I wouldn't do it without a catless uppipe. A new turbo is a lot more expensive than an uppipe.

To turn, or not to turn? Or should I at least buy OEM replacement rotors?
