Im curious as to whether or not if my stock k03 turbos on my 2004 audi a6 2.7tt s-line have an adjustable wastegate? How can i get more boost out of them?

 

Upgrade the ECU and DVs. That'll kick the car's output up to roughly 320hp and 365tq.

 

You can crank the waste gate or weld it shut, not recommended. Buy a mbc/ebc and turn that shut up. Not recommended. Or do what Jeremy said and get a tune

 

Messing with waste gate adjustments would destroy system calibration. But you could do this:

It would relieve the control pressure from the N75 valve that’s supposed to open the waste gate.
Start with the valve closed. As you gradually open the valve, more and more of the control pressure will be bled off, keeping the waste gat closed. This would yield only limited boost increase because eventually the ECU will put the engine into limp mode. For more, you’ll need ECU modification (chip).
