The main reason I let Stan do the re-map is because his explanation of what was required to delete DPF was the most convincing of anyone I spoke to.

As would seem obvious removal of DPF massively reduces back pressure on turbos, this means how they spool up needs to be carefully controlled otherwise they will overspeed readily with obvious consequences. There were also a lot of things Stan noticed when researcing/ developing his DPF removal software that changed when the DPF was removed that needed correcting to ensure the engine and its ancillaries remained reliable. He is a very interesting man to talk to on this subject!
