Man this really woke up the 5.0 it sounds like a big 4 barrel carb with no air cleaner. It is a little loud when going up hills or mountains, I think it actually sucked to much air on one climb up the smokey moutains and the Ecm could not compensate fast enough and my check engine light came on. It was almost like to much air at high altitude I let off the gas and all was fine and light went off. I did gain some power and fuel economy. Thanks for the fast service auto anything.
