going study the service history when i get home, but you know how they work, they jus wack a big oilley stamp on a book saying they serviced it. i kno henk can do a personal map but every engine is different, i could take a dremmal to my airbox and make it respond differently and without a RR there is know way of a accurate map, however i like the idea of doing my own data logging and fault clearing, so i will get one with a personal remap but evenually when i get the cams in and the zorst setup then it will be RR time and a propa remap so ye, logic dictates, inlets first, but most important is cambelt atm!
