When I hit a hill or the engine gets idle it gives a weird tune like if something is loose. It's a great Tune but when idle it's a weird sound.I have a 5.7 liter Hemi and put a Mopar Air Intake but it gives a weird sound when engine is idle?
different air intakes can change the noise of the motor when at idle or full throttle. if you like it keep it, if not try something else. something could be loose though so do a good check over everything that was installed
