What do you think about buying RS2 turbo, injectors and "contact" them: http://chips-ur-s.com/Entrance.html for Stage 3 setup 
"Stage 3. This level of performance enhancement is usually referred to as an "RS2 mod". Our Stage 3 mod uses the same VMAP (or Bosch PT if available) as Stage 2 but software is provided to accommodate higher flow RS2 level turbos and higher flow injectors to accompany those turbos. Maximum boost levels of 26-28 psig are available. Performance is improved to the 360 to 380 hp level. This, of course, requires the addition of an RS2 turbo, exhaust manifold, and higher flow injectors."
Is this really possible to get without "realtime" tuning?
