theory on 350 HP problems.

[RVTRKN]

I think I have the problem solved, at least in theory. The 305 HP C&C has not had any problems with the regen issue and I believe it is because it emits less soot pre DPF due to the fact it is less HP. When you chip a Diesel it will smoke more due to more fuel injected and can not burn all the fuel, so if D/C were too increase the size of the DPF on the 350 HP version, it can hold more until regen can burn it off

The example can be found in a pleated filter, the larger the pleated folds, the more filtering surface you will have which allow less restriction. The DPF has a pressure drop sensor just for that reason to let the computor know it is time for regen due to pressure drop.

I think that woud be the hardest, to trick the system when modifiers remove the DPF and there is no more pressure drop and would record it until downloaded by the tech who would void the warranty. By increasing the size of the DPF you would still have the soot filtered but there would be less regens and would allow time to burn the soot off before the filter gets clogged. Just think of the MPG increase if the DPF were enlarged

TDR members, what do you think of this theory?
