When I cleaned out mine - things felt a lot better too, but the measurements were IDENTICAL. It's akin to the placebo effect ;-)! I have NEVER seen any measurement that showed any change. Most people change several things and don't take a before and after measurement, but when those niceties are followed - THERE IS LIKELY TO BE LITTLE OR NO DIFFERENCE unless the intake manifold ia more than 50% full! Every measurement I've seen supports that (and I have received almost a dozen reports where careful measurments were made and I've done it twice myself).
