Got an 08 6.4 that has lived quite well for 380,000 miles. Went through 3 re-gens last weekend and then went into reduced power mode. Codes are P246C, P2452, P2463 Has anyone cleaned there own DPF and how do you do it. Can anyone in the Columbus Ohio area flash my computer and turn off the re-gen so I can straight pipe it? Any way to straight pipe and trick the computer not to re-gen? How long can I drive it in reduced power mode? I know, I know Just get a damn tuner. LOL
