okay so i went to the dealership today to see if they could re flash my computer for the charger and they say it cant be done so i was wondering if any yall had info on what i could do or should do.... and how my car would run with the charger on with out the re flash?

 

Ummm, they only have reflashes for the stages for the 2.0. None exist for your car with that application. You will have to get a custom tune. Search for Trifecta on this site, that should point you in the right direction.

And yes, you definately need tuning before you run a supercharger. If you tried without it, it wouldn't be pretty.
