Message	the exhaust valve and intake valve are open at the same time for a short duration in order to fill the cylinder more quickly (and therefore more completely) at high rpm's. Our VTC system creates this condition. Whether or not it could actually happen on a Z32 depends on the choices of the ECU, habits of the driver, throttle vs rpm, etc etc... but why risk it. Daily driving a TT is like ordering your favorite pizza for breakfast lunch and dinner. It's not healthy and eventually you will lose the magic of the meal. Sometimes you just have to have some meatloaf. My new meatloaf.... 1994 Black Honda Civic DX :D what? It looks a little stumpy, but fits great in the hand! (n/m) - ZEngineer 12/12/06
