    Boost

    Have searched a bit and can not find anything specific about my problem. I sometimes will be getting on it, and usually I will get to 17lbs and then stay there for a bit. Lately, I've been getting to 17lbs while still getting on it and it will just drop down to about 5-7lbs and just stay there. It doesn't do it all the time but just sometimes. Anything anyone knows? any help appreciated thanks. =)

    Maybe limp mode. Could be a boost leak, but doubtful.

    See if you can pull any codes. I can think of several possibilities:

    1) Something is causing you to go into limp mode.

    2) Your DV is either defective or you have a leak in the vacuum/boost signal line that controls the DV.

    3) Defective N249 valve that is sticking open.

    My bet would be on #2. Take a close look at the control lines from the intake manifold/N249/DV and look for any cracks/splits/etc.
