The graph is a little bit messed up because the max power is in 4th gear, and because the top of 4th is above 155mph, the car limited itself, thus causing the drop in power in 4th gear. Despite this, the numbers were still: MaxTQ=648.3ft/lbs and MaxHP=approximately 440whp. Once we get the limiter removed, the car should put down 500 hp and 700+ft/lbs of torque.
