I'm actually the first with a production kit (other than SEMA cars) and I put down 444.5 on a dynojet. There is PLENTY more left in the car but the fuel pump just cant keep up with it. With fuel system upgrades, long tubes and a smidge more boost I expect my car to make around 500 to the tires. For more info check out the power adder section of LS1GTO.com
