| How critical is the DPF??
Hey guys, I was just curious on the significance of the DPF on the newer duramax, because my tuner just disabled it on an 09 I believe. He disabled it through the factory comp and manualy removed the filter from the exhaust. The truck (according to the owner) feels faster and picked up 4 mpg. Have any or you messed with this? Sounds like a good idea for the power and mpgs.
