| by 2750 while the other 2 pulls were started after 2500 and were only around 5psi at 2750. Looks like that blue TT is getting away with high boost running 17.5 psi on 91 octane. 
Here is my 15psi graph with the same mods as the blue TT but I was only able to run 15psi safely. Although I have a J&S knock controller so I hit 17 on the street regularly without issue. It seems knock for the most part occurs on long 4th or 5th gear pulls. If you look at 2750 you'll see I'm only at roughly ~5psi as well. For whatever reason that blue TT is getting into boost quicker.
