    Sorry, I missed your question when I looked last, I haven't found any more info on it, here is the link where I found the article......

    I guess that contacting Siemens (Australia) is the best option.

    Really?! 500 seems pretty high considering the cost of the vehicle. I think 415 is a deal. I'm really looking forward to the GXP.

    Most will be 500 after a few mods.

    Exactly. 40 or 50hp is really not that hard to coax out of these engines/cars. As is extra torque.
    I'm running 450hp and 450tq with a CAI and tune only on the LS2. The LS3 is clearly an improvement over that again.
