I just picked up an '04 MCS as a daily driver that was tuned/modded/etc by Behe Performance (aka Lucky Dog Garage) per the previous owner and can tell you this car goes like stink. The dyno sheets I was given showed 210 at the wheel, which at the crank factoring in a 20% loss is 262hp!
I'm going throu the list of other mods done to it besides a tune; I know some head work was done, an under drive pulley, and a cam. From what I understand, the tune was what woke the car up. If I get around to it, I'll post the dyno sheet.
