What do you think I should use for my VE when figuring plots for the map. Its a pushrod motor with ported and polished track-heat heads and intake and a Lunati cam, 70 mm tb, and 73mm MAF. It should varry with rpm, right? i.e. .95 @ 6000 .9 @ 5500 .85 @ 5000 etc... or would you just use a midle of the road base of say .75 all the way through ? If varrying with rpm what would you suggest for base, say.. .70 or .75 down around 3000 ? Any help would really be appreciated.
