How critical is the DPF??

Gearheadfab · 07-02-2009, 07:41 PM

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.

a great idea for mpg and power.

a bad idea if you want a valid warranty from gm .

mine fell off about a 1000k ago, only issue is that the truck sounds way more badass so I drive it way harder..

Well, if anyone in south florida is interested the guy I know that had it done said the tuner offers a DPF delete package, which includes computer and exhaust mods. The shop is mobledynosolutions.com if this helps anyone out.

Myself and the other sponsor offer it as well.

Mine has been gone since 2k.

Interesting didnt even know what a DPF was until a couple of days ago. I didnt know the mod was so popular. Thanks guys.

Had an 08 with DPF 2500HD LTZ CC SWB SRW 4X4
And now have 09 3500HD LTZ CC LWB DRW 4X4 EFI Live and DPF Delete.... And you can tell the difference.

No Regen, better fuel economy, and the larger truck is faster and more responsive than the smaller short bed truck.

The DPF is criminal, uses 15% more fuel, $25% more when towing, all to remove harmless but visible carbon in the exhaust. Greenies again!! Getting it wrong again!!

Anyway, it is fixable... Cheers from Oz, lone Ranger
