OK, so I  have the RS2 performance mods, should I be thinking about
adjusting the  spring?

Chris,
 My wife has the full RS2 setup on her car and does not have a boost  gauge 
so I left the spring alone until last weekend when I hooked a gauge up  just to 
see what her setup was making. Well, with the spring in the stock  position 
the car is making and holding 28psi to around 6000 and then backing it  off to 
22psi. This is much more boost than I had expected so I left the spring  where 
it is because at this level the car would start overboosting if the spring  
was tightened at all. Now on my old car with a much larger turbo I had a 
stiffer  spring in as well as four turns and running the same SW as she is from 
Pastore  would boost to around 26psi and hold 24 to redline. Even though the car 
was  making much more power it was making less boost I assume because of the 
large  compressor wheel bringing in a more efficient charge of air. Anyway if 
you don't  have a boost gauge get one before you tamper with the  spring.
