You know the drill: take out your plugs, take a picture of them, then put them back in.

I have the same issue, except I have changed my plugs and it still does it. Mine does it at wot even if I'm not on the rev limiter, also when I shift gears fast??? I know I need to check my tune so I'm trying that next. It's Been happening for about 3 months just haven't had the time or money to retune.

I'm currently trifecta tune and have after market DP, Intake, FMIC, and Upper charge pipe. If I take it to the dealer and let them check it out will my aftermarket stuff be an issue for warranty work?
