Default Found and fixed boost leak. It was the TBB, but now the boost seems to take forever to build.

I am now building all the way up to requested boost (before actual boost would be 400mbar less than requested,) but now it takes almost 3 seconds from lower rpms (1800) and almost 2 seconds from higher RPMS (2800) to reach 2100mbar. When I shift I loose all my boost. I don't think this is normal. I don't recall having these issues with my Tiptronic S4. I checked the BPV's and they both hold vacum, although its seems to take very little suction to pop them open. Still no boost spikes when I shift so don't think BVPS are bad. Any ideas?

If you have a leak, boost will *appear* to come on quicker. Also, shifting with a leak=boost spike.

Default Well, Its not appearance because I logged actual Vs requested boost pre and post boost leak.

Its definately taking and unusually long time for boost to build. Is this the difference between tip and 6-speed? if anything I thought it would be the other way around.

I have never gotten into boost on a TIP, but I don't think there is any difference.

tips don't lose boost between shifts like manuals do.
