For example, a FMIC actually drops the amount of boost required to produce the same amount of power.
On a side note, my buddy is coming into town with his 370z. We'll be heading out to the houston raceway park in baytown -- I'll try and post some vids.

Yes, my friend run his 335 several times at SIR Tucson (3,100ft.) and then at San Antonio TX (400ft. aprox.) His best run in Tucson was 12.6 @ 111mph for 12.7 @ 109mph in SA.
Mods were exactly the same: Procede V2 and Intake. His runs were pretty consistent, he drives the automatic version.
