The Cobb Accessport system just makes it so easy to tune. Many enthusiasts do not even get into a platform if a Cobb AP is not available for it or will wait specifically for the Acceport to come to market.


Look at these OTS (off the shelf) pump gas results for a MKVII GTI. Let's start with the baseline:


Now the OTS tune on 91 octane:


You will notice peak horsepower doesn't increase a huge amount but look at that torque gain of 45 lb-ft at the wheels. On a Mustang dyno, that huge.

The numbers improve further on 93 octane pump gas:


That's 31 whp over stock and 65 lb-ft of torque over stock.

A custom protune will get even more but very nice gains here especially down low in the rev range.
