Wait... your first post's synopsis is this:
You don't own a contour and don't know the compression ratio. (FWIW: the most SVT's are 10:1)
You state that anything over 9.8:1 requires "race fuel"
, but somehow the engineers at SVT state premium is fine for our 10.1 (or higher!!)
You finished up saying that we should always go by our "seat of the pants" feeling BECAUSE that MEANS its working. Never mention that just because something FEELS right, doesn't mean you don't need to tune, etc (granted fuel is not going to affect air:fuel, etc, but your general premise is flawed..)
Nice.. but I think I'll file this away under "whatever..."
