From what I have heard messing around with a boost controller on these cars are not worth while. You're better of getting an Ecu tune.
Tune. Stage 1
Tune
Don't do it......power increase causes a slippery slope of "modbug"
Stage 1 increases boost by almost 50%. Such a good deal @~$850 with install. If you wait for their seasonal sales and find a shop that'll do the sale tube for free you're looking at $600.
