2017 ram 2500

So I read everything on DRD site and I'm looking to purchase a tuner

My question is do I really need the sound tune?

I seen he said it the same HP but with sound.

If I don't get the sound how does the truck sound than with a 4 inch exhaust with no muffler?

Also anyone have a 2500 with factory rear air ride? If so are you having any issue with the heat from exhaust by the airbags?

Last but not least I tow my 8k pound boat what is the big difference between the 13-19 MM3 Tuner - Lite Option and the 13-19 MM3 Tuner - Complete Option Package With Accessory Options?

any advise on a tuner would be greatly appreciated

Also if anyone has a site i can get my EGR delete and the other stuff I need from I would appreciate it.
