I did. But if I remember you had to leave early. After you left and everyone was through, myself and a few others paid extra for a second dyno run and thats when i got in a few more runs with and without the cap in the KKM. It was a suprising increase in power from capping the end of the filter.

I never tested the idea with the MAF screen, but I tried it once at home and the butt dyno said there was better throttle response and a little more power especially in teh low RPMs. The dyno is the best place to test it out since you get real numbers rather than just relying on the sensation of acceleration during road testing without any kind of test equipment.
