calling any revo dealers or anyone really

on the A3 it was available for drive by wire cars, so most post 2000/2001. I'd assume as all S3's are DBW it could be available. Although can't you just buy an SPS3 and adjust boost and timming yourself?
 
what car is it you've got (inc engine and year)?
 
yes stage two is available but hardware requirements vary depending on if yours is an A3 or an S3 :)
 
hi carl mines a a3 got a 4 bar pressure regulator full milltek with 3" downpipe with cat replacement and k&n filter
 
that's a perfect spec then! you're ready for stage2 :)
