When you're flowing that much more exhaust, it does make your engine run a leaner, but it should compensate with extra fuel. Once it learns, it will be fine until you lose battery voltage and the Keep Alive Memory (KAM) is wiped. Your Dealer doesn't want to have to deal with any consequences that could come from there, so they're playing it safe. Which, is smart to do for any business, really.
