I'm currently at 12.0:1. Very rich. If I bumped it back up to 13.2 or so, how much power am I looking at? I dyno'd 300/301 on a 96*/50% humidity day.

Just seeing if a tune or tweec would be worth doing or should I just wait till the vortech gets put in.

If I remember right my A/F was at around 8.5 when I did a dyno tune . When Lidio put it up at 10.5or11:1 my power went up about 25-30 horse on the setup in my sig.. I don't think he touched the timing..

I guess I would leave your car alone until you do the Vortech..
