no, no codes...one thing is, earlier that day, it was fine and went to 14, when it whent to 14, the

boost gauge would sort of flutter at 14, like vibrate real fast.

But when you're at part throttle, is the boost always at 10, or does it vary between 0-10psi?

If it won't go higher than 10, you'll probably want to start looking for boost leaks, starting with the BPV.

I bet it failed. don't even bother getting the TT. get a Bailey.

I'd find a local buddy who still has a working stock one laying around just to see if that's your problem.

:-) and, you can get 5 baileys for the price of 1 bailey, since they carry a lifetime warranty.

Probably not bad if it holds a constant boost. If it's stock...

I think the stock valves are spec'ed to hold up to 10 psi and then open. It probably just can't hold the extra boost.

When people say the BPV leaks boost, is that under WOT, or b/w ****s?
