im pretty sure the dealers havent got the equipment to re-map!! only read diagnostics and update stuff ! if you speak to vantuner he is sound and will tell you how it all works

plus if anyone gets stuff done by him and your not happy with the intial map he will re do it or tweak it for you no quibble i know cos i had mine done again due to the fact i asked for power which he did and it went like a train

but i was not strong willed enough and tempted by a heavy foot

so i spoke to martin and asked if he could tweak it which he did and so far ive got more grunt than standard its a lot smoother and about the same economy
