Default Do I HAVE A BOOST LEAK?? Datalog info

So Ive been Datalogging and From what i see things dont look bad?! I dont really know much about the parameters but I know what a good one looks like for the most part. the only thing was my boost. I never reached target boost (target= 19.5, I got to 16ish) also my boost was somewhat all over the place building (non linear, up and down) and then on the taper to redline it was up and down. I think my topmount might be slowly leaking. what do you think?

Go to the doc in Google Docs, click on "share in the upper right, and set it as either publicly available, or viewable by whoever has the URL.

How did you determine that boost target is 19.5psi? In any case, boost target changes with elevation and air temperature. If you check the data item "TD Boost Error (PSI)" in your log, the error is <1psi once you hit full boost. It looks like boost target is ~17psi tapering to 15psi.

There is a bit of Fine Knock Learning above ~5000rpm but doesn't look like anything serious. P0037 is related to the rear O2 sensor in the downpipe. It could be the sensor or a small exhaust leak at the gaskets.
