Think you may now be flogging a dead horse Shane, the boom years were 5 to ten years ago, you would be a brave man to take an ECU out of a high tec Beemer, Audi, VW, with all the emmission control systems built in, let alone what VOSA or whatever they are called now will introduce in the future, the DPF straight pipe bypass is now a fail, lots of motorists who thought they had found a get around, are soon going to be severely shocked, they then come back to the garage that knocked the guts out of the DPF and had their tuning company delete DPF software, saying " I took your advice,I now have an illegal car, what are you going to do about it ".
