headers will outperform any form of ported manis or plog by a large amount. the headers versus one another, not so much. any headers are better than no headers.
i do not know how to use an aeroforce as i do not have one, but you should really be shooting for it to say 0 all the time. the likely hood of it actually being 0 all the time is probably minimal though, especially without a good tune. by good, i mean someone in the passenger side scanning and tweaking for like an entire day of driving around. my last tune session took 6 hours or so and i didnt even get to finish up the tune as far as peak power goes.
