    I guess I should have said that it uses the OE xdf.

    Here is a log I took today. I alternated between starting it with the MAP hose connected and disconnected. You can see which is which because with it disconnected the MAP stays at 100 the whole time.

    If you can look at the log and give ANY feedback at all it would be appreciated.
