I would not go near jamsport with a enemys car as I have seen first hand some of their major very expensive cock ups , bluefin is a learning program but if you want a spot on map tailored to your car then you need a live remap not a plug and play thing, only a few specialist companys around that are very good like MSD at blackpool or pumaspeed/superchips have a good rep too with the 170, heard poor things about dreamscience and their over optimistic rolling road figures lets say as they are better known for the mk2 st/rs
