AAh Ok, this sounds much more likely to be the issue then. I am fairly happy with my knowledge on setting up with regards to CAM and posts/coding so was fairly happy that was right.

but with the tuning I literally had/have no idea about what I'm doing! I'm away at the moment but when I get back at the weekend I will grab some screen shots of the tuning software and my settings for you guys to have a look at if you wouldn't mind?
