Boost=Maifold Pressure?

[BGolden]

I've become addicted to this site,now I want to hot rod the old girl a little. Is "boost" manifold pressure?

Are gauges recommended for a baseline to calculate performance gains, or would there be times you needed to back off throttle to prevent damage(after adding hi-po parts)? Thanks, Barry

Yes to all of your questions.
