Would adding a 6.0 PSI supercharger help ?

Thx - stuck with the 6.4 for now, so any advise on Minimum Supercharging (6.0 PSI Max) greatly appreciated. Thx
If you're towing with it at high altitude,the last thing you want to add is forced induction to it,not unless you like putting pistons in it after every tow.As stated either learn to live with it,or spring for a Diesal.6.4's at the best of times don't like boost,throw a load behind it,and pull that load up the side of a mountain,is pretty well gonna put enough heat into the cylinder to expand the rings to where they butt together,and then it's pretty well instant broken pistonWould adding a 6.0 PSI supercharger help ?
Given a naturally aspirated engine loses about 3% for every 1000 ft above sea level. So at at 8K ft the 6.4 Hemi could be down almost 100 hp.to address the issue in a more timely manner, check your engines advance function and use higher octane fuel.
Can’t afford to trade, but willing to trash the warranty, spend big $$$$ on mods, then spend $$$$ on a replacement engine after towing heavy boosted?
This will not end well.
Just how much weight is being towed, at what altitude, and who are you trying to keep up with?

As for higher octane fuel in higher altitude, the lack of oxygen sorta negates the need for it.
What do you mean by "NO POWER"?Would adding a 6.0 PSI supercharger help ?
For what it'll cost you to put pistons and rods in it,so it'll handle high loads under boost,you could buy a Cummins.You hit a mile long grade and you're using boost to compensate for the power loss,and you'll be putting pistons in anyways,lol.3.83 gears towing a 30 foot fifth wheel. 8 Speed Transmission spends most of the time in 6th gear and will not hold the speed limit, any small incline and it will jump down to 5th or 4th (Average elevation 6000 ft). This a Stock 2022 6.4 with 14K miles on it. Engine is in perfect running order (empty this truck is almost like a hot rod)

^ This. Zero trouble 5,000-9,000ft up for me. The only thing that is a letdown are the brakes. Gonna get some heavy duty brakes on next spring.How high are you? Was at 9000 feet in wyoming with my 6.4 with zero issues last month.
