Bruce Nunnally Posted March 7, 2015 Report Share Posted March 7, 2015 Livernois Motorsports video showing before/after dyno chart for a tuned CTS Vsport Before: 338 hp / 354 ft-lb of torque After: 409 hp / 434 ft-lb of torque All the VSports are automatics, and rated at 420 hp at the crank. with a 20% transmission losses for the auto, that would be 336 whp expected at the wheels; this one measured 338 whp. So an increase to 409 whp / 0.8 would be ~511 hp at the crank.
