I agree with Demon completely.
I can't stress how important it is that you dyno on the SAME machine EVERY FREAKING time. A dyno is not something you use to generate numbers so you can jerk off to the highest number, a dyno is a tuning tool that allows you to gauge your gains/losses. Every single dyno reads differently and comparing your numbers to some other guys numbers 3 states away is meaningless. You cannot accurately gauge your car's power after running on three seperate dynos. The data is meaningless in my book.
