Interestingly, they happened during a regen on one of the cooler days, but were cleared nicely on the fly by the Edge Insight. A great deal of the towing was in 95-105 degrees during the Texas heat wave, so I am pretty satisfied overall.
I am still puzzled by several hings.
1. What is the relationship between the PSI differential and regeneration?
