Weird. I know when I got my tuned after pretty much the same mods as the OP, my tuner told me that these cars come with a crap ton of torque management. The drive home after the turn, I got on it hard at a stoplight to see what it could do and man I was surprised how rough it was! In a good way of course....

But anyways, to really take advantage of your headers, and get rid of that damn torque management, get a tune!!!
