DPF on w/ high idle mod?

There have been many threads about the high idle mod, so I was just wondering if everyone that is doing it has their DPF removed. If you are going to leave the DPF on until the warranty is up, is it pointless to do the high idle mod? It would seem that running at a higher RPM at idle would only clog the DPF faster...

I ran mine for probably 30 some hours on high idle with the DPF on. Kept it warmer in -25 weather. Definitely cloggs the DPF though.

Yes it will work with the dpf on or off, but it works better with it off because it will clog the dpf faster and force it into regen. Its a great cheap mod though!
