So my Focus ST is tuned with a Cobb Accessport. My $.02 on this is that the Accessport is a GOOD tool and really sets the stage for some great tuning options… but the off the shelf Cobb tunes are pretty weak compared to what can be done on it really.
I paid about $300 to get a guy who really knew what he was doing to do a custom tune over email back and forth, and with the same car it’s light years better than the Cobb tune available for the same car.

Cobb tune = an upgraded factory tune, but should be generic for all cars.
Custom = a tune actually made for your car, your needs and your goals.
Personally, if you’re going to bother, I’d look at XRT (or someone similar who knows the platform) to get a custom focus tune to really get the best results.
