If you're running 98 octane fuel then I would recommend our 10psi pulley kit with your setup. Worse case though you may have to go back to the standard chip/memcal, but would certainly be worth it :)
For the "HOLDEN SUPERCHARER BOOST UPGRADE For SUPERCHARGED V6" what would be the recommended pulley size on a factory VS supercharged commodore, cats removed KNN air filter and Chip?
