DD15
Hey guys. I know this is primarily a cummins site but I've learned a lot about my Detroit just by applying Rawze's info. Anyone else here run a Detroit?

RE: DD15
I had a 2013 Western Star with a 560 hp DD15 for three years, had the DPF filters changed out at 8,000 hours and that was it.
Now have a 2016 Cascadia with a 600 hp DD16. I recently pulled the Delta-P sensor and cleaned off the soot. It looked pretty good and cleaned up easily.

RE: DD15
I have a 2011 Cascadia with a DD15, 800K miles. I bought it with 725k on it. I did replace the dpf at 760k but that's all I've had time do with the emissions. It doesn't have def on it.

So far I've pulled the crossover tube & MAP sensor & cleaned them.

RE: DD15
Before I purchased my Volvo two years ago, I tried a 2016 Cascadia with a 400 hp DD15 and the DT12 transmission. I was a company driver at the time and the mega fleet I work for was going towards a majority Cascadia fleet.

Let's just say, that's why I purchased my Volvo.

(Actually, I purchased my Volvo because the Cascadia also had the "On Guard" radar system installed. Don't get me started on that crap system.)

Not knocking the DD15. I've heard pros/cons about them, just like the ISX. However, my Volvo with 400hp and the Cascadia I tried at 400 hp, it just felt like the DD15 power was flat. It could also have something to do with the rear end gearing. My Volvo is a 3.42. Not sure what the Cascadia was. Probably a 3.20 something.

I'd love to try a 500+hp DD15 and see what it can do.

Yeah, I'm not sure what the hp setting is on my truck but it doesn't pull that good.

I know what you mean about the on guard system. Must unsafe thing I've ever had on a truck. I don't have it now but my last truck did.

I used to have the ISX cm 870 but the crank broke. Now I have the DD13 in a Cascadia.
