Don't have the bike or tyre, but a general comment is that the structure of street and track tyres are different meaning they are meant to run at different pressures. One of the reasons road tyres are built to run at higher pressures is that one of their jobs is to pretect the rim when eg you hit a pothole. There aren't many potholes on track, so this function is unnecessary. The point is that running track tyre pressures on even very sticky road tyres may not be the best option.
It might be worth calling Pirelli to ask, or check out Dave Moss Tuning on youTube. A data point that might be useful is to know the hot pressures for spirited road riding, and then to make sure the track hot pressures don't go past that
