Tune recommendation for towing at elevation?

[BoilerUP]

Setup:

Have a 2017 Silverado 1500 CCSB 4x4 5.3L 3.42.  Truck has a bone-stock drivetrain, is my daily driver and I have no issues with the way it pulls my 32', 6100lb dry travel trailer...well under all spec'd weights.  I live in Southern Indiana and about the worst hills my truck sees while towing are Jellico Mt. along I-75 east on 40 over toward Pigeon Forge.

We are planning a trip out west this summer pulling the camper, and the route has some elevations in the Rockies approaching 9k ft.  Have talked to the wife about possibly upgrading to a 2019 1500 5.3L NHT for more smash while serving as a daily driver, or possibly a used 2500 6.6L for future use pulling a fifth wheel...but at this point she is putting the kebosh on that idea since my current truck is owned outright.  Doubt I can get the Boss's permission for a $6k blower, either.

I've always thought tunes were kinda silly for the way I use my truck, but looking this trip I'm wondering differently.  Came across the SCT BDX, and the dyno'd 5-6.5% increase in torque with 87 octane and 7.5-13% torque increase with 93 octane looks could be worth the $400 cost...especially if I can tweak it once I'm back at home for better response/MPG.

I have looked around here at tune threads but clearly am missing something, so I figured I'd do that naive guy thing and start my own thread... :-)

Looking for opinions on the value of the SCT BDX or any other comparable 5.3L mail-order tunes <$500 for towing, especially mile-high and above.

Thanks in advance!
