timing?

The OP posted this in the Racers Forum so I figure this was a max effort question.
Yes you can tune your vehicle all kinds of ways from being conservative to squeezing every bit out of it. Who races their car with the VAC Advance hooked up?? Nobody I know. Why stroke your engine to be conservative is my question?? Sounds like an oxymoron or a play on words at its finest. "Waste of an engine"! Kind of like the guy who has 1000HP beautiful car with all the go fast goodies who idles it everywhere or trailers it to car shows never cracking the throttle open unless he is parked in Neutral... "Waste"
