Cheers :-)Each coloured line represents an individual run on the dyno. The top chart shows 3 unique runs with the baffle fitted - the average of the 3 is 125.93BHP. The air/fuel chart shows a dotted red line which is the supposed optimum ratio, the same 3 runs are plotted on this chart with the colours corresponding to the power chart. Where they are under the line the mixture is lean, and over the line it is rich. The middle chart shows another 3 unique runs with the baffle removed the average is 133.97BHP, the air/fuel chart is unfortunately not to the same scale but to my eye it is a lot smoother with less fluctuation between lean and rich. The 3rd chart is a combined report of the 6 individual runs, unfortunately the air/fuel chart is too small so is confused but the Torque chart clearly shows the 3 runs with the baffle out on top (more torque) and the baffle in underneath (less torque) and again to my eyes the charts show a much smoother delivery of power with the baffle out.
Hope that helps.
