very true m8
as far as building engines go i find it easy as do most of us on here
but when it comes to spec and technical details i like to ask the experts and follow the advice and guidance of my tuner . i havnt got a fookin clue about mapping etc etc and wouldnt even dare tell anyone i have the foggiest about any of the techy side of things thats the side of things i would rather pay for the experts knowledge on
