I think BlackBear did this to mine, I only noticed lockup today in 5th and 6th and then only under certain situations and speeds.

If anyone has issues with their contact us form on their website, the guy i chatted with.
justin (at) ftiperformance.com
I actually emailed him last night asking about his converters.
Mainly went off that this is a tow vehicle.
The reply i got was that their converts start off @ a 2600 rpm stall.
And not really for towing because of that.
My thinking was the higher stall would be helpful for towing, especially with a 3 disc lockup clutch.
I was actually thinking a nice 3000 stall might be nice...
Any thoughts?

I havent drove the truck too far like this, but so far i really like the change.
Just that 1-2 shift where it would lockup really bogged the truck.
Using the tow button helped a bunch, but it's nice not having to use that unless i want engine braking and higher shift points.

What did you end up going with?

All this talk about stall got me lost. Hopefully OP made some progress on his journey.
For someone that wants boost, what TC would be recommended/price vs something better than stock that does exactly what stock does? What is the disadvantage going with beefier TC and not able to take advantage because you decided not to go boost? Will that affect driveability or just wasted $?

Does the flex plate need to be changed also or still use the stock flex plate and just three bolts?

You don't want a high stall for towing, too much heat. You don't want a smaller converter for towing either for the same reason, stick with 300mm.
Stock JMBX stalls at about 1600 rpms but this really depends on the power output of the vehicle. This converter will stall higher behind a 6.2 and higher still as power is increased.
I forget what the Sierra's stalls at and mine for that matter but remember that the Sierra's was higher. Will have to check them both again and write it down!
The poor man's way to check for stall is to stomp on the gas from idle and see what the converter flashes to on the tachometer.

I went with a circle D 300m unit on my 6l80.
double disk unit.
they no longer offer it, and now they have an even nicer triple disk converter in the same size.
mine was about 2200-2400rpm stall.
I'm probably right in the middle of that, closer to the 2400.
so far no complaints.
the new one offers a selective stall.

So with the Circle D unit did they recommend the stall or was it set for the 2 disc version?

+1. I have a CVC model BU60FHD in my 2012 which I use for towing. It's a factory unit that's been properly remanufactured with a billet housing and stronger lockup clutch. It's designed for heavy duty service and CVC probably remanufactures more torque converters than anyone else. It came recommended to me by my local indy transmission shop. I have about 20K on it now and it's been terrific.

for the two-disk version they didn't have any stall selections.
They also didn't recommend going for a smaller converter due to the weight of the vehicle, and the fact that I planned to tow my boat up a steep canyon road made it even worse.
For my use I'm happy with the stall selection.
It has been fully replaced by the triple disk one.
That has a selection of different stalls to work with, but not many options.
GM 300mm Pro Series 6L80 Torque Converter
This converter is a fantastic upgrade over the OE 6L80 Converters. A daily-driver friendly stall speed coupled with billet components makes this a no-brainer for your mild cam 6L80 truck build! Converter Diameter: 300mm - 12" Stall Speed Options - Factory (1800-2000rpm) up to 2600rpm Billet...

What I understood, due to the size of the converter it relays to how much load it can handle.
+ the heat thing, more volume = better.
Also due to the larger size of the body, it can't do higher stalls.
