    A4 or M6?

    Automatics usually show less power than M6 on dynos.

    I would guesstimate around 290 -300 RWHP considering that it is an Auto
    Also the CAI really won't show up on a dyno.
    I've seen several Lid and catback Auto's dynoed and most were still shy of 300 RWHP,

    Just do the math to figure out the diff from M6/M5 to a A4. There is different #'s to use. If I was not running to the store for Super food... I would get my Dyno Shts and post the #'s, maybe later?

    A4's work fine. They do better if U have your shift points changed, and I do not ever use my traction control, that is just me. More fun that way!

    HP isnt always accurant. Track times tell the real story. Get some headers and a stall and a tune and tear it up. dont worry about the dyno
