Do any of you (1.8T chipped owners) change the wastegate spring when you do the chip swap? I heard that you have to change the wastegate spring in order to bring up the boost. Otherwise, the result of a chipped 1.8T is not going to be significant.

The stock turbo on the A4 uses an internal wastegate. The mod you are mentioning only works on external wastegates.<p>Ali<br>1.8T 230hp

The ECU controls the wastegate, there is no need for a stiffer spring, besides, the K03 has an internal wastegate with a rod, so theres no spring to change
