For example, Temperature, Type of Dyno, etc. Same thing can be said about the track. For example, Temperature, Skill of Driver, etc. As I have also stated that track times and dyno numbers are informational tools used to access teh car's performance.

Realistically very few...I would venture to guess 1% get an engine dyno after every modification. It is really not practical.
