I wonder which is the best way to go
Is it better to have your engine blow up on a dyno or some where down the 1/4 mile.
What happened to the times of run it, pull the plugs make your best estimate and adjust fuel timing etc.
observing what the engine is telling you,
When she runs sweet ( a little dark in the exhaust ) its all good.
When it goes F&n bang it time to start over again.

Camo I recon a blow on top would fit the image
