Is it boosting back to normal now or was this just during those runs were it started running low boost
The two lines on the graph are 3rd and 4th gear, timing looked normal, +6 Degrees. I attached the full Log for this session.

Boost is back to normal, it would only reduce pressure when the water temps exceeded 235F, as soon as it was lower it would return to high boost pressures.

The Limits of the JB4 shouldn't come into play here since I was on Map 0.

This is a very good Idea, I may be back at the same track in Sept, If I go I will swap the coolant to test.
