    Apparently all we can do to our V6 to make it go faster is push the peddle harder? Is the cai and exhaust all we can do? I would have thought there would be a few more mods available by now. I understand they are just V6's but come on, these will out run some V8's already. Nothing wrong with tinkering to give it a little more, even with a V6.

    The G6 GXP came with the LY7. Maybe some of the mods for it will work for yours.

    My Roto-Fab CAI seems to have made it faster. I really haven't noticed a mpg gain.

    There's an intake plenum available in AU for them. Claims a HELL of a increase in power.

    I thought I read somewhere that they were going to develop a supercharger for the V6. Did I dream that or really read it?

    Over a year ago I heard that but I don't think it ever happened.

    I heard the same thing. Developed in OZ but there was some question on placement in the US version of the car. Had to do with clearence (Right hand vs. left hand steering) Crazy Paul would probably know.

    It's really just a 3 step process:

    1) remove 3.6L engine and set aside
    2) insert 6.0L or 6.2L engine in big hole where 3.6L used to reside
    3) turn egnition and enjoy!

    I talked to a guy from Magnson superchargers out here and he said he was trying to sell the bussiness plan to his boss. Guess it never went thru as he never called me to use my car for the prototype.

    It may be also due to the fact that no one has broken the code for tuning this thing. Our computer is completely different from every other LY7 version.
    Have you thanked a veteran lately for the freedoms you enjoy today?
