    I don't believe in boost + high compression in a pump gas scenario. Even race machines, I've seen better results with reasonable compression + very high boost (turbo)
    S/C is another story with efficiency dropping so quickly and HP loss through driving the S/C. Stock compression for pump I think is better in general.

    For a completely maxed out M90 on pure race fuel high compression is the way to go.
