Hi guys- been lurking for a while now trying to get my mind around all of this. I'm no diesel mechanic nor cumputer guru so if my questions are stupid, please set me straight.
1) If you do a DPF delete but put the sensors back in, why will it set a code -- too much air? Common sense would say that the sensor would think the filter was clean all the time and not need a regen.
2) I do the DPF delete but the computer says the truck needs a regen so it opens the butterfly on the EGR. If the passages are blocked on either end via EGR delete mod, (but the EGR is left in place) exhaust can't pass through, but the computer can still communicate to the EGR and it knows the vavle is open. It should not set a code because the device responded as it should. Best I can tell there is no flow sensor in the airsteam of the EGR assembly so it can't know that regen really isn't happening. I am assuming there is a position sensor (like the TPS) on the butterfly valve so the truck knows whether it's open or closed.
Lastly, why would you want to remove the air to air intercooler (that is the cooler you guys are talking about, right?) I thought the cooler the intake stream, the better.

Okay guys -- set me straight
