Whiptastic,

I suggest that you may have triggered the traction control when you dropped the hammer the last time. The 'lag' you were experiencing was most likely the ESP and traction control reducing your engine power so you wouldn't spin the tires excessively.

If you want to really FEEL the pick up of this vehicle... be on the freeway at about 60 and punch it and HOLD it until you are hitting 90mph. When you let off the pedal you will feel the seat push you back out.

If you still feel it's not as responsive as it should be or has a seeming 'lag' to it after the throttle reset, I'd suggest finding another one to test drive as the one you tried probably has a bad IC Pump.

The torque on these cars is simply amazing. Not to mention having the same slalom times as an SLR.
