DPF Cleaning
I understand that putting a good load on the engine will help keep the DPF clean. I use mine as a daily driver, and have two small hill climbs on the trip to and from work. both climbs are about a half mile, and I can run the boost up and get a decent 70mph run. My drive averages about 30-35 mph. I am about 17% idle hours.
You guys think those short blasts help, hurt or no difference.

No Difference.
Watching my soot% I see it climb when I've got my foot in it and the turbo boost is high.
I see the soot % drop when my EGTs are high but my boost is low.
For example, pulling a trailer up a 6% grade, EGTs climb to 900°, turbo boost is close to 20 psi and my soot% increases.
vs, pulling trailer down a level highway or a very slight grade. EGTs stay at 600-700° but my boost is 5 psi and my soot% decreases.
vs driving empty down same highway and my EGTs are 450° and my boost is 5 psi and soot% stays the same or very slow increase.

Interesting question. I don't have a way to monitor any of it, but I've been of a similar belief - get the turbo PSI up when climbing hills. I guess it doesn't really matter. If there was a way I could see the soot build-up and EGT's it would be neat to monitor. I'm not sure that in and of itself is a good enough reason to spend more $$ though to get a meter

Yep and you gotta keep the gunk out of the turbo. Good plan.

The OTR drivers I know just add it to their inspection list, just another thing they have to do so they can make a living.
