    That is a considerably larger cam than what you had before, so you need either a tune (to set your idle) or you need to drill a hole in the TB to let more air in during idle. I can't remmember if there is one already in there and you just need to enlarge it. But if you are able to do the tune that will fix your problem and while tuning they should be able to sqeeze a couple more ponies out of your cam. I have a similar cam waiting to into my car but as of today I have now first hand knowledge. Is your car auto or 6 speed?

    does the 04 GTO have the throttle by wire like the corvettes? can't remember. if so, you'll either need to drill the hole larger and/or have more tuning done to increase the idle rpm and adjust the throttle kicker.

    Don't drill your TB. Get a tune.

    I've always heard either the option of drilling the TB or a tune, what is the reason not to?

    I guess it's a matter of preference. Here's a thread about it.

    What you've done is installed a cam where the intake and exhaust are open at the sametime for a greater amount of time. While this allows the motor to rev higher, and the tighter LSA creates more power in a shorter range. It's caused a loss of vacuum at idle, and fuel must be removed from the fuel maps in this rpm and vacuum range. It's my experience from tuning motors that you'll also have to increase the fuel in the midrange to accomodate this new found power. I'd buy LS1edit and make these changes myself.
