i just bought this car about a month ago and i know direct injection motors do tick but how do i know its the normal tick compared to bad ticking. also question with boost how much boost does stock panamera turbo put outm i notice mine at 15.6 psi n taper down to 10-11lbs at redline. any suggestion i dont think im leaking boost nor my turbos are bad. just trying to figure it out before factory warranty is up.
