Cobb Stage 1 OTS Accessport MKVII Volkswagen GTI 2.0 pump gas 91 and 93 octane dyno results

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.

20whp (nearly +10%!) going from 91 to 93? That seems off to me...

You would have to ask TPG Tuning.
