Why is the date 2014 on the graphs? Torque is a bit mad! Whatever mate, bottom line here is it's done and you're happy with how it sounds and there is no droning. Weighed up between having a flat spot or not having the manifold, given what you've said, I think it's worked out ok in the end. Shame Paul couldn't get it mapped out though. Very much looking forward to a ride in it soon.
