So I have been learning and playing with this tune for ever. I dont really know what am doing but have been getting as far as I can without being super unsafe. I have DPF, SCR and EGR deleted. I would love to turn off the post injection but can not figure out what maps to modify. I also have a bigger then stock turbo and have been trying to get it working as best as I can. If anyone knows how to remove the post injection or how much I can actually advance timing that would be great. It would also be good to know what timing maps are used during what times.
