I'm curious if there is a standard for measuring improvement in your tune/build. For example it was common to do 60-100 pulls in the Mazda while in 4th gear. This is what the tuners liked to use while logging and doing revisions and the drivers used to see marked improvements. Obviously using 0-60 or 1/4 mile times would not work as there are too many factors. With the 60-100 I would just calculate DA so I could correct and wasn't pissed "like i was the first time" when I lost time due to atmospheric conditions. Has this group settled on any standard like this for the sake of tuning and measuring the performance of the car while removing as many outside influences as possible?
