Exclamation EXHAUST GAS TEMPERATURE on 2008's

lets just say you have no choice but to keep the dpf functioning, so it has to be a certain temperature during emmisions and has 2 sensors for that. shouldnt egt's not be as much of a concern on the 08 as older diesels are. I would think ford/international would have designed the turbos/engine to be more robust to meet the new standards. Also wouldnt the sensors keep the engine from destroying itself even though they are much further then the down pipe.
if not im whiping out the sawzall.

I have heard the CPU limits the EGT to around 1100, can't remember for sure. Marc said something about it on the radio, Marc.....?

with the DPF on EGT would soar over 1600 deg now with it off I have to really push it hard with a very heavy load to break 1400 deg. And do not take a sawzall to the thing unless you reprogram the ECM or it will just get stuck in regen mode and blow white smoke everywere!!

over 1600 and the ecm will power down until it drops below 1200 , but I have already saved enough on fuel to pay for the KEM in 1 month , so I can afford to pay for any real mishap just from the fuel savings alone. got 11.2 last week LOADED and driving it hard and thats with it bogging down everytime it goes into idle for some goofy A$$ reason. But if I cycle the switch quickly it will just roll smoke and take off. I can't wait to figure out what this problem is and see what the MPG goes to then.
