Thanks for the log. It is much different looking at them in this format and takes some getting accustomed too.
I fixed a boost leak I had a week or so ago and got a surprise. I run a solenoid that controls boost through link. Anyway, it is indexed by gear and rpm. The table covers 1st, 2nd, and 3rd. I had this table set up to produce 30lbs. I went for little ride and when I got back, I hit 39.4lbs of boost. Do not know if the leak was that big or the air is that much more dense but the extra load of 4th gear in low rpms and pulling from a 3rd gear table was a major contributor. FWIW there is another fail safe table in place, but it was not dialed in and the error correction was not put to use. This was only for a very quick second. The BOV was fluttering at this time so I was taking it easy. Here is the screen shot.
FWIW, this is an HX35.
