Running 200bhp, make sure you see the proof! Mine's running Superchips bluefin and didn't really gain any topend, but transformed the thru rev range drivebility, which I'm happy with as you use it more day to day.
Don't know the spec of car you going to see, but be surprised if chiping it made an extra 30bhp, or Ford would of done it to the ST200.
Even the standard ST200s I've seen rolling roaded struggled to get their magic 200, and they have different manifolds, cams, injectors, throttle body etc over the ST24.
Not saying it can't be done, but it the exception rather than the rule and if Ford struggled to make the ST200 get to 200ps then it says alot.
