Staying true to the fact that they have become the official supplier for ECU upgrades, aero kits, brakes, exhaust systems, and a few other modifications for Saab models on the US market, Hirsch Performance has unveiled one of the projects they have been working on. The Saab 9-3 sedan by Hirsch Performance has been unveiled at the 2011 Chicago Auto Show featuring some pretty impressive little extras on it interior and exterior.
The specific model revealed at the show received a 30 HP upgrade, but that is only one of the options provided by Hirsch. Crack open a Saab 9-3 with a 2.8 Turbo V6 engine and Hirsch can pump it up to 300hp (up from 276 HP). Other engine setups can get updates from 140hp to 300hp.[...]
