I bought my QC with a Volant CAI and a Magnaflow and it's strong, real strong. My silver QC had a CAI, headers, hi flow cats, Magnaflow and DC performance stage II flash, and I swear my new truck is quicker. The problem is that I don't know if it already has a flash. My previous tune came with a small DC Performance sticker on the computer. But absent that, is there anyway that I can tell if something has been done?
