Well I tried again but never heard back from Williams so gave up (not sure i'll bother again) and called in to Mek Motor Sport in Cheltenham today. Dave there did an hours ECU work to get the figures somewhere near. Transformed it although I am going to get him to do a remap next week as it was so far out. He couldn't have been more helpful and I'd certainly recommend him. I'm impressed by the improvement already so we'll see how it goes after he's done his stuff.
