Best Averaged Runs on the Same Day Testing

Please keep one thing in mind, I go to the extreme to keep my Dyno calibrated to the Data Analyzer used to collect the Dyno Data ( www.performancetrends.com ), this is way more accurate then the "eyeball" calibration method used by some. I have personally spoke to a few Dyno owners who use that method, and it's a little disappointing to hear ,,,, But when doing comparison runs on the Same Dyno it really doesn't matter what the numbers read, but more so the difference in the "before" and "after" graphs. Considering the same testing protocol and testing equipment was used the difference in percentages will remain the same.
