I have a 2010 facelift C6.5 3.0t. I have a GIAC stage ll + pulley tune, dynoed at 404whp & 404tq. The dyno shop told me that the AG6 trans isn't tunible, and thats what is to limit my motor. Can you guys tell me what are, if any, the advantages of this trans, and is their any hope out there for me?
