Methanol, Race Gas, Boost, Timing... Too many Variables !

[fe9_fe9]

I just was thinking, on a dyno and with very limited time.. Because time is money here, literally

So how do you deal with all these variables on the dyno?

Throw timing at it. Check the graph for dips or rough sections. Pull the plugs out to check for signs of detonation. Adjust accordingly.
