Here we have a typical stage 2 Legacy GT. The modifications on this car include a COBB downpipe with a cat and the neckdown removed, an SPT intake, the car was tuned with a COBB AccessPORT, tuned at 16.5 psi.

One of the questions we are often asked is if it is worth getting your car Pro Tuned or if the Off-the-Shelf maps provided by COBB will get you the same power.

COBB’s base maps are a nice improvement over stock, however one of the limitations of the base maps is that they have to be compliant for all 50 states, all the various fuel formulations found through out the country, etc. Basically what this means is that COBB’s base maps, although they do provide power levels above the stock output of your car leave something on the table.

To try and show what kind of power is left on the table, on this dyno chart we are showing a comparison between a Verocious Pro Tune, and a COBB base map. The black run is the Verocious Pro Tune, and the red run is the COBB base map that comes with the AccessPORT. Andy made more than 25 whp and 30 ft. lbs. over the COBB base map with this car.
