I think the tune in that example is the most important. Of course you cant look at the tune and the cams seperately as they are adjusted on eachother but just the cams give only a gain above 6.8krpm(if I look at the graphs correctly) which is to be expected. Normally: bigger cams (more opening at longer duration) means gain in high revs and loss of torque in low revs. With that tune they correct that pretty nicely, probably by setting the timing earlier. But that does give more strain on the rodbearings because the bang comes earlier before TDC so the bearings get more force before tdc to cope with.
