I had something similar and I raised the MAP side of the VTT to fix it at the recommendation of G Huggins. Worked like a charm.
You may want to post a log or at least log where the issue is and take a look at it vs what you have in the current VT table on the MAP side. Goes without saying that the MAF and VVE need to be dialed in.
