Your right the debate will go on and on. I'll tell you my story, I ride an '07 Hayabusa, all tuning was done at 500ft elevation. In July, 90dg temp we tuned for production class for Speedweek, set the record at 211+ with a best one way speed of 213+. Came home changed exhaust, couple of other mods to put the bike in APS, retuned at 95dg, went to World of Speed. I dont think we made a run when the temp was above 80dg. Set two records,213+ & 214+, best one way speed 219+. Took the fairings off for World finals, set two records 194+ & 200+. We did nothing to the tune for World Finals and most runs were made at below 50 dg. Could I have run a little faster if I had been able to log a/f and adjust, probably. Could I have done all this manually tuning a set of Lectrons, highly unlikely.
