well, i went to the dyno for the first time. My car stats are: 03 GT 2V, 5-speed, 53k miles, no engine mods, flowmaster cat back. with that said i put down 236rwhp, i was amazed. I talked with the guy and we figured a 15% frictional loss. that puts me around 280 at the crank..hmmmm. the only thing I have done lately is change my plugs (AGSF32C, coppers) and I run amsoil oil. so maybe i have factory freak....
here is the dyno sheet
