Here's a few more graphs, interesting correlation, though could be unrelated, is that when boost peaks out there is often the drop in TPS. Maybe the air intake is a problem and the throttle is being cut? but that sounds very strange if that were true.

First graph is from a stop through first, second and third gear and I let off the gas when it switches to fourth. (shift are at where the boost bottoms out) -- See how smooth TPS is once boost goes back down below about 23 psi? I think that's around 4k-7k where it's looking pretty damn good. Rarely do I see it that smooth in third. Base barometric is about 12.7 at my elevation.
Second graph is during a forth gear pull so rpm increase is only about 2k rpm during the WOT, maybe around 3k-5krpm but interestingly the tps doesn't cut out during it, even though boost is pretty high.
