yeah they are simple i was a bit confused by all the stuff too before i got mine i ended up putting up a thread saying right start to finish tell me everything lol.
maps are different, personally the way i look at it Henk at fastchip as the man when it comes to mapping cars and if its still andy from GDi at ktec then i wouldnt touch it if you paid me (and i love k-tec and their service too, such a shame)
ive got a fastchip 98ron map with launch control on my ph1 and it made a brilliant difference to the mid range pull
