DPFE (EGR) Sensor delete

[ittybittyfds]

OK, I have searched the forums and not found this topic discussed. One of the biggest complaints I have had with my truck since installing the flowmaster exhaust was the loss of throttle response and lower end power. I have been told that the loss of response is do to the DPFE sensor common on Fords. The DPFE sensor regulates when the EGR opens up and dumps unburned gas back into the intake to be reburned. Since there is less backpressure with the new exhaust the DPFE sensor is reading more exhaust flow.

I was told that there are ways to do a DPFE sensor delete but I couldn't find anything.

Has anybody heard of this before?
if so care to educate me a little more?

there is no way to do a DPFE delete on the 6.2L, it does not have EGR

I'm not sure that I've read of any members having a reduced throttle response with their new exhaust...

itty, the DPF - Delete Particulate Filter & EGR Cooler are diesel engine components. Them other forums apparently think the Raptor's 6.2L is a diesel, which I have been told by numerous folks that my truck doesn't sound like a diesel. Doh! cuz it's not a diesel engine.
I haven't heard of anybody losing throttle response after installing an aftermarket exhaust on their Raptor. Now, if you do headers, you'll need a tune for sure...

Well Hell, he is talking about his diesel not his Raptor. Doh!

How'd he deduct he was talking about a Super Duty?

DPFE (Differential Pressure Feedback EGR) sensor is actually a gasoline engine component

The DPF(Diesel Particulate Filter) is a diesel component.


So yes the OP could still be referencing a gasoline engine and not a diesel

DPFE - Differential Pressure Feedback sensor. It meassures the flow in the EGR tube and converts this to a signal for the computer.


It is not specific to Diesel engines!

and no this did not come from another forum. This came from a real live ASE mechanic (no not a ford mechanic)

Which truck are you talking about, then? The 6.2 in the Raptor does not have EGR.
