Hi Mark,

are you basing this on the fact that Luck is reading the manifold pressure from live data, if so i can see now where your going.

I assumed he actually read the physical vacuum with a gauge which if i'm correct i make it slightly low but still ok.

But if its live data based then its way off as it eqates to around 10.5 inhg and then i'd be checking valve timing again.

thanks
