Stock k03 adjustable wastegate?
 

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?

You can buy waste gate springs at 034 motorsports that will raise you boost but I'm not sure if easy to get to the waste gate actuators on an s4 a chip is the best way but it's more expensive.

Do my turboes have an internal or external wastegate? The springs on 034 motorsports are for "Wastegate spring for Audi external wastegates which came on Audi turbo cars from 1980-1995.5." Will they work?

Sorry i didn't read, i just read factor Audi waste gate, You can either chip it or run a mbc but that's not recommended because it takes away from the livability.
