I read that in the sport mode that there's an overboost feature which brings the torque up to 192ft/lbs momentarily. However, there's no mention of the HP. Does anyone know what the HP numbers are with the overboost feature engaged? Having owned a few turbo charged cars and tuned them tells me that typically, the HP numbers are far greater than the torque.

For instance, my previous car which was a 1997 Toyota Supra Anniversary 6-speed put down 597 RWHP and 555 ft/lbs of torque on low boost running pump gas. Needless to say I upgraded the turbo :-). Every single time I dynoed the car the HP VS torque was usually around 7% to 8% of the torque.

So if I had to guess going by past experience the HP number would be around 205HP (crank) going by 7%. OR...going by stock numbers 192ft/lbs = 190hp? Since stock the numbers are 177ft/lbs and 175hp (however things change drastically as boost is increased) Has anyone dynoed or gotten numbers to confirm this? Also, does anyone know how much the boost is increased? I know when I switch the car to sport mode that it is a noticeable difference so I was curious.
