TurboXS isnt really a good idea for 4G63 unless you have a VPC or some kinda GM MAS , or stand alone that'll allow you to vent to atmosphere without problems.

Yep, very true. I am on the fence when it comes to venting. I do not do it but I know of several people who do with no problems. The only problem is though, TXS is not the best BOV on the market and they will leak at idle eventually. The spring wears out really quick. I use one on my 420A and when it started to go, the car had turbo lag like holy hell, takes forever to spool. On your 4g motor though, when it starts to leak, it will no longer want to idle and possibly die between shifts. The only way to Vent a 4g with the minimal problems without doing it the right way is to use a SSQV or a Type S becuase you can adjust them closed.
