EGR ???

[IBEDAM]

Doing DPF/CAT Delete with SCT Extreme Livewire tuner. Goal is to improve fuel mileage not to mention stopping the damage that I hear the DPF ends up doing to the engine. Here is my question --- This tuner allows for EGR to be deleted or turned off. First what is EGR ? Do I need to turn it off ? I hear to delete it you must pull cab so that is out ! Any knowledge or help on any of this would br appreciated ! THANKS !

i assume you are talking about a 6.0, in which case you DO have to pull the cab to delete it, however, if you find a good mechanic that knows what hes doin, it IS possible to do it and NOT have to remove the cab. i recently had a man do mine, he did the egr delete kit, new heads, head gaskets, and head studs, and during all of this my cab stayed on.

Egr stands for exhaust gas recirculator, it is a device that takes exhaust from your engine and reroutes it back through the intake. Manufactures put this on to meet NOx emissions requirements. The problem with diesel egr is that all the soot in the exhaust is routed back through the intake and really gunks it up. It also must be cooled by your engine's coolant so it also makes your engine run hotter. I would definatly delete it if you can, on the newer trucks it is much easier to do, and you will see benefits of: better fuel economy, more power, and cooler engine temp.
