Question on deleting DPF

[JBB1970]

I have a question about doing a DPF delete on my truck. First of all it is a 2010 F-250 6 speed manual 4X4

I read a post here previously that stated if you removed the DPF, you must put a programmer on the truck to keep the truck from trying to regen constantly.

This makes no sense to me as it would seem to me the truck would NOT regen ever, since there would be no build up of soot in the exhaust filter. As it is my truck has only gone into regen about 5 times since I bought it in January. I have 9200 miles on it.

Am I wrong in thinking that the truck will only regen, when the soot builds up or is there something else that causes the regen process?

Thanks in Advance for the info.

The computer is programmed to make the truck go in regen regardless. That is the reason you will need a programmer.

Truck will regenerate every 667MI regardless of soot load. In doing so, it will look at the DPF pressure pid, and go "What the ****? There's no pressure here. **** YOU! We're goin' into regen, and we's STAYIN THERE!"

what's the working pressure on the dpf pressure sensor on f450 6.4l powerstroke engine

It does not base regeneration solely on the DPF pressure.

You say it goes in to regen, no matter what every 667 miles? Based on that my truck should have done so about 13 times, so it must not be doing it for long, since I have only seen it do it about 5 times.

My dealer service manager told me that the truck will only do it when the computer deems it necessary. This is where my confusion comes in. The service manager also told me that by getting good fuel and not hot rodding it, the truck wont regen as often.

The message only displays for a few seconds in my 2010. If I am on the highway (running empty) the regen process in hardly noticeable. It would be easy to miss.
