When i dropped my SCR and DPF, that pipe appeared super clean on the inside, so I didn't do anything. My forced regens take atleast 1.5-2 hours. My DPF temps go way high, sometimes 1200 degrees.

After my forced regen went past an hour, I told myself I was going to shut it down at 1.5 hours because I didn't know if that was normal or not, as it was the first time the truck has ever had a forced regen performed. And I really didn't want to throw 100 gallons of diesel out the stack. My DPF temps were up into the 1200 degree area. It never goes that high driving down the road. Usually hangs around 1000 degrees.

I was getting a check engine light due to excessive regens, so the last thing i did was have the DPF and SCR cleaned. That was 1500 miles ago, passive regen 4 times

I remember Rawze saying "about every 300 miles or so" was normal. That's why I was starting to get concerned when my truck was regenning every 175 miles or so. Never had a check engine light for it. But figured it was hurting my fuel economy, so, I should probably do something about it.
