I don't quite understand your problem?

Sounds like the wastegate isn't opening or something. You check the vacuum line running to the actuator?

Okay are you free revving it in neutral and it's building boost? Yah they'll do that sometimes.

If not, what the hell you talkin' bout? ;)

If you're talking like 5 psi or less, that's pretty normal. I haven't seen a t.d. that doesn't do that. Also the boost gague may be off.

Same here. I actually have never owned a TD that would do it.

with a D-valve, 3inch SV and 3inch downpipe on a Garrett turbo I could nail off like 10 psi free revving that, it made for some sweet turboXS RFL bov action :)
