No tune at all? How do you know it doesn't have a flash from previous owner?

Does it hunt at idle? (AC off)

If you have it, put back in a paper filter and clean the MAF sensor. Check and be careful of the MAF o-ring when you do.

Check all the vacuum hoses. Replace anything crispy especially near turbo.
Correct/any pill in the BCS/wastegate T line?

Air leak is easy. Check the hoses for visible cracks, cuts, crispiness loose clamps. Spray carb cleaner around the intake hoses including intercooler Y pipe. All clamps clicked on air box? Plastic turbo inlet giant corrugated thing is common failure point.

Borrow a cable and log it. Boost gauges lie.
