Default It's the solonoid that controls boost. The ECS "race" N75 is actually a stock part....

on a different Audi. I think it just holds a few pounds more boost. If you're chipped, the little K03 is already near it's limits. Skip

Default

It does it by controlling when internal waste gate opens and how fast it opens.
