Pros:

1. Moar powers

2. Includes Cobb Accessport ($500)

3. Unicorn Status, would be one of if not the only US Spec Fiesta ST to have been tuned at an official Mountune shop (they only have them in Euroland)

4. Straight-up it'd be more fun and might get me back into the habit of respecting the FiST again cause I'm getting entirely too comfortable taking corners at 80 mph

Cons:

1. Cost, it'd cost me between $1200-1300 to have the work done at an official Mountune shop which seems expensive as hell especially when you consider that $500 of the money is for the Accessport tuner so really it's like $800 for the Mountune intake system and install
