My car is tuned and I got lucky that the dealer did not say anything. I have stock intake but that is pretty much it...
they replaced one injector, one plug and the coil. The car actually runs a bit smoother than before so this could have been a problem for awhile...
Under hard accelerations, at times it would feel like it would skip a beat, now it is gone.
