Reading all post I agree that surround sound doesn't nearly as good as normal. That being said, the mid and highs sound great, the bass sounds great great in a lot of music but can be boomy at times. I too get rattles from the rear, I know some is in rear power window because it gets worse if I open the rear window while hearing rattles. I can fix rattles. I want to know if I need the update or if I already have it?!? I took delivery of my truck 12/31. The dealer says they couldn't have registered the truck with FIAT CHRYSLER or DMV if there were any TSB that haven't been applied to my truck. My HK sound isn't quiet at all but if there is an update to improve more of course I want it. I also ask about the transmission update. They don't have proof this stuff has been done, they just say the truck was built after the updates and/or everything has been updated or they would be flagged by the VIN and I couldn't take delivery. Right now I'm working on getting new headlights. It's rained a lot since getting my truck. It was raining when I left with it. I've been able to wash it once. I noticed a ton of moisture in passenger headlight after washing. I know people have had trouble with dealers telling them it's normal. I simply stood my ground and said there is no such thing as normal moisture in the headlights of a $70K truck especially since those projector housings are full of electronics for LED headlights, markers, running, parking and DRL. They ordered new headlights for me. Just waiting for them to arrive and be swapped. I just hope it's assembled like factory. I honestly hate this is even having to be done but glad I didn't have to fight to get these expensive headlights replaced. When this is done I need wheels and tires ASAP. Looking at Nitto 285/55r22 on stock or aftermarket wheels. I need a bed cover but don't know where to start. I want a Cold Air Intake but can't find one yet for 2019 1500 5.7 eTorque. Looking at Carven exhaust, looks and sounds nice from their videos. Last thing is a true TUNE. Never had issue with good tuners for GM but not having luck with RAM 5.7. Can't find anyone. Only thing I can find is the Pulsar piggyback PCM add on that some say are great, others say it really does nothing. Any help for any and/or all my concerns would be greatly appreciated.
