DPF DELETE HELP

[maquino]

I have on 08 6.4L duty. Is removing the dpf and adding a straight pipe in any way harsh on the engine? is it better for the engine?

Is it true that the fuel mileage gets better?

I know you're new to the site but there is a search function that would answer all your question on this topic. But yes it is better for the engine.

ok, thanks, do I have to do any egr or egt deletes when I remove dpf? I thought I read somewhere you have to get either or.

No you do not need a EGR delete but it would be better if you did one.

You do have to have a programmer to delete either one.

you need a programmer to delete anything off the 6.4. By removing the DPF you are helping the engine. During regen diesel fuel will contaminate your oil, which is not good for the longevity of the motor. Deleting the EGR will prevent the EGR from going bad, and potentially hydro locking your motor. That is the short version. If you live in a place that does emissions a DPF is easy to put back on once a year, EGR is a little tougher.

With H&S or spartan tuners when u do a dpf delete it turns off the egr valve, the coolant is still present to cause issues though. EGT stands for Exhaust Gas Tempature, which is just a way of reading how hot ur egt is. Nothing to delete with that and with a screen style programmer it will read ur post turbo egt sensor.

Removing the DPF/EGR does not hurt the engine in any way, in fact, it helps it out quite a bit. The DPF adds unnecessary back pressure as well as the regen cycle which are both terrible for your engine. The EGR recirculates part of the exhaust gases back into the engine for a second burn, imagine running a marathon, breathing through a straw, hooked to your butt.....not good.
