G'day all, I was just reading the post about boost solenoid maintenance and I've gone out to have a look at mine to find that the hose off the solenoid goes to a tee piece, but is not hooked up. Now I've found the hose its meant to be connected with, but its been plugged with a bolt. What might be the reason they've done this? It' a 04 BA, XR6t. Aftermarket intercooler and piping. I've only had this a couple of weeks and it's the first turbo'd car I've ever owned so any info would be great. Cheers.
