Is this ironic coming from a guy who drives a 550hp sled on the street every day?

The new Z06 will have 200+ ftlbs more torque than my car at a much lower rpm. With drivetrain loss my car realistically is putting down closer to high 300s (450ish hp) at the wheels. The stock mapping on the XFR even set on TRAC TC makes the car pretty driveable in lower gears. A lot of the throttle is dialed back for most of the rpm range with stock tuning (apparently you never reach true WOT), which is how the XF//RS and XJR get 40+ more horsepower. These engines were run at 700-800 hp during testing so there is plenty left in them if you wanted to see those kinds of dyno numbers but it would be ridiculous to have that much power on the street in a RWD car.

A pulley'd and tuned XFR is up closer to 500hp at the wheels / 420ish torque with a reasonable power band. I doubt I will swap pulleys but I would consider a tune if I could pick up another 30-40hp and shift a little of the power to the left for passing punch.
