Knock and AFR are the things I monitor most, if you haven`t got a good wideband AFR gauge in the car already it`s a good investment.

You can here knock on some engines, on my Mitsubishi if I heard audible knock the engine would be a gonner already though, I tuned the Golf for audible knock and that worked pretty well so it`s swings and roundabouts to some extent.

I prefer road tuning to rolling road tuning to be honest, 1/4 mile running is a good option for datalogging and tuning at higher loads/speeds.
