I don't think its a DIT thing, I think its a "Good Job Subaru" for sizing the exhaust just about right for the turbo (and putting it down low). Stage 1 is the entry level tune for a factory spec car with factory parts. brought his Stage 1 Ford Focus ST to our Dyno Day in Colorado. It is worth mentioning that those results were on the Cobb 93 octane map, but we were running 91. On the Stage 1 map, that increased to 345 ft lbs of torque, and 284 hp, which is a lot for just a re-flash of the ECU. This must be a DIT thing because I see nearly the same exact thing with the Focus ST and Fiesta ST dynos between Stage 1 and 2. When we put our 335i project car on the dyno to get a baseline, the car made 270 ft lbs of torque, and 243 wheel horse power.

With dyno proven maximum gains of 6 whp and 5 wtq, this Focus ST intake offers a respectable. The reason being that there aren't any major gains at all above ~4600rpms.
