Temps
I used to be tuning by temps but theres to many variables that change, temp humidity, track surface, engine load, all of these and more. Its good to keep an eye on it, but like the others were saying if you have smoke trail, and make good power, your good, I wouldn't pay too much attention to the telemetry stuff, I'd personally question the accuracy of most of them. I work at a Calibration lab, and theres alot of ways companys can make a statement that miss leads poeple. Go with the smoke and the way the motor feels.
