    maf or sd tune? check your o2's nick is notorious for cutting those
    I would have expected more but if that is an ls-1 intake you have at least 15rwhp with those mods.

    C5, he didnt cut them but then unscrewed them when he tuned it and then pput them back on. and i dont run a maf.
    mods are in the first post
    here is a chart that of the before and after the heads and cam.
    you can see it flys stright up and past the last


    the gain is on the average IMO and research.
    most people with a better intake and port stck TB and pulley is around 420-425. so IMO with a fast IM and TB set up with some advancing, i`ll be up there

    Very cool, as soon as i sell this 02 mustang gt vert I'm using the proceeds to buy a 95 bmw 325 and ls1+t-56 and pay off some bills and then my tax returns finish the ls1 swap.

    went to the track a week ago and am very unpleased.

    my old times were 12.6@ 115.5(best) with 330/336.
    new times are 12.7@ 118.89 with 409/368.

    im stumped on this, i think there has to be something wrong. i even tried to ease on it so i could hook up but still wasnt getting the times i should be getting.
    how can 3k only give me 3mph faster. Yes,i know i need slicks or at least DR but still.
    the guys ive seen online with just a cam are running high 11`s(11.8`s) at like 120.
    yes there on DR but is that really holding me back that much?

    what did your 60's look like? That mph is enough to get you well into the 11's.

    Post all the info given on your time slip, the 60' is a crucial bit to have also. Especially compared to your old 60'. Looking at how slammed your suspension is that's really got to be hurting you.

    For every .1et in your 60' translates into .2-.3 down at the end of the track.

    ^Yep that slammed look you got going on isn't helping at all w/ straight line traction.
