I threw P0402 - EGR Excess Flow - 4 times during my 2500+ mile trip last week. I cleared them each time at fuel or pit stops and the truck ran fine anyhow. Thing is, I am blocked and fingered and on a Predator 85 tune. I've never had that EGR code during the 20k+ miles it's been in there and the Predator tune has been in for 35k+. I'm wondering what changed. I WAS running straight #2 w/o BIO for the first time in a couple of years. Averaged 66 mph and 17.3 mpg. I also noticed some HEAVY soot at the infrequent times I leaned into it but that's cleared up some since I've 'cleaned' it a bit more often.
