So like the title says. Car is an LS1 Corvette. Car came in running very rich but no codes and nothing else wrong with it. We installed the A&A supercharger and the car was running very rich still. We pulled fuel by the MAF airflow table several times and it still doing the same thing. We pull anywhere between 10-15% at a time and the idle is sitting around 11 afr. Up top it doesn't seem to bad but the car doesn't seem to be making the power it needs to either. Any ideas?
