sorry, just catchin' up with your replies...ok, so it is a lean condition, thus the tune. i know about a tune for e85 and i have no intention of going that route until i have the whole e85 setup AND the tune. i guess im wondering if there is no proven gain from TB and ram-air because nobody has really tried it? i saw several people claim they were going to dyno some NAs with TBs but i think ive only seen one or two graphs and i dont know if those were pics from manufacture sites or somebody legitimately trying it for themselves. and what is the differance between the air pressure in the intake with a fan on a dyno and going...oh...say...85mph? is it significant? im just throwing these out there. i truly dont know. "MAF scaling with the tune"...hmm, gonna have to read up on tunes! once i have the ability to start dinking around with my tune, im gonna have great fun right up until i burn my valves or melt the tops of my pistons!
