Any suggestions as far as the max safe rpm? (Hopefully higher then my cam will make power), other tricks i can try go.get more power before I make the.trip ( 400miles) to the only dyno in state? Iv been considering a new.intake, air gap or.single.plane maybe? Whatever mods i do tho.I don't want to hurt mpg... car got 23mpg on its.first 500 mile trip.

The dyno should determine at what rpm your engine makes maximum power so your shift point can then be determined. I would not advise changing anything at this point. An airgap intake will not gain you much and a single plane intake may help top end power but at the expense of low end torque. That is not a good tradeoff for a street-driven car which spends the majority of its life below 3000 rpm.
