I once spent some time playing with LC's in my prevoius motor and I agree that it is hard to tell the difference. I did stop watch runs on a section of road to make comparisons. It think that I could do it better now as the Zeitronix records time as well as rpm and AFR. So if I did WOT runs on exactly the same stretch of road under similar weather conditions then I should be able to measure accurately the acceleration.
