Regen Frequency
Just trying to get an idea of how often everyones truck goes into regen..I have a job 1 truck and before the reflash, she did a regen every tankful, so about every 250-275 miles or so. Now, with the new dpf and new flash, about every 500-600 miles she will regen. How about everyone else?

I got 1800 miles and never noticed a regen. I'm sure it must have happen sometime on the freeway, but not during city driving or idleing time.

I have over 3xxx on mine and have not noticed it yet. But then agian 80 percent of my driving has been highway miles. Isnt there supposed to be something on the display on the dash that states a regen is in process?

regen is a mode where the exhaust system injects fuel into the dpf (diesel particulate filter) and burns the particles to clean the filter. You will notice the rpms rise to around 1200 at idle and increase slightly also when driving. im no expert and this is very brief but this is what has been explained to me.

If you have a pre turbo EGt installed you will see the regens as the EGT temps increase significantly. They occur more at city driving speeds. You may be surprised at how often regen takes place.
