Wow! Thats very impressive for a bone stock C5Z. I would not doubt a intake/header car running 118mph but stock running that kindof trap is an achievement and also a freak car most likely.

I never ran my black one so nothing to compare to but your weight is on par to it. The black one weighed 3050 w/ half tank of gas. My C6 weighes 3140 with 1/2 tank of gas on same scale.
