I've just bought the kit alloy bell mouths (trumpets) for my 07 Daytona. Number 3 cylinder runs a shorter bell mouth to 1 & 2 and according to the book I should set #3 fueling up different. Do I have to do this does anyone know? The only way this can be effectively done is to have a lambda sensor for each cylinder so I can see the differnce in fueling and adjust accordingly. Any help please?
