cheers for the fast reply, the blokes were going to be dealers for gotech, they have a test station which can simulate a running engine and it didnt work on that too so they left it alone after that. They map loads of top rally cars round my way so they know there stuff and are highly recomended. Ive spoke to mark a jamie b4 and they are a great help, also simon at sitech, but im after a non biased opinion if you know what I mean. Ideally someone who is using mfi pro x or has mapped it before

I looked at a few companies abroad and one of them has discontinued selling gotech due to quality issues? which is a tad worrying
