[s-cars] safe boost limits

[James Murray (LMC)]

I thought if you controlled your boost via manual boost controller you are
effectively bypassing the ECU boost control? The only advantage to
"chipping" at that point is having more agreessive fuel map so you don't
encounter a lean condition at higher boosts. Or am I way off base here?

	No, The WG spring has more to do with getting these unacceptably
high levels
	(unless engine totally built) than any SW. I have some VERY
aggressive SW and
	it doesnt run this high when not in overboost.
