Drove a weak GSX

The reason it's so slow is because the turbo probably isn't even building pressure, so you're basically driving a turbo car, without the turbo. That's why it feels slower than stock. If he hasn't upgraded the fuel pump or injectors yet, you definitely need to do that, and also get a logging device set up ASAP before you boost at all. Depending on exactly what model of T4 it is, that could put down some pretty good numbers. Like crunchy said, 6 psi isn't even on the compressor map, it's too big of a turbo to be runnning a mere 6 psi and be anything efficient. You'll also want to upgrade that BOV too eventually.
