I've been running g the SC 3865 on just the 93 tune for the last 6 years without touching torque management, shift points, etc... I tow a 2000lb 5x8 enclosed trailer at least twice a week for my home reno side gig.

That being said, would I benefit from selling the 3865 and buying a Henifever equipped Diablo tunner for the added HP when I'm not towing.

A lot of people have been more than satisfied with the Diablo with the hemifever tune. I have not tried the 3865 so I can't compare them, but I sure was happy with my hemifever set up. I'm sure that others will chime in.

I cannot comment on the difference between the two on these trucks. However, I used to have an ol' 2001 Ram with the 5.9L V8. Had the Superchips at first, and later got a SCT with Hemifever's tuning. To make a very long story short, Superchips customer service does not compare to Sean's (Hemifever). His tuning is also better.
