Good advice.
To answer your question, without getting too technical, you should not set the CLB to 820 in closed loop. The closed loop fuel control will not function correctly with the CLB THAT HIGH!
As others have said, you could allow the "learn" protion of the MASTER TUNE adjust your VE's. Then run in open loop with a command A/F of 13.8.
My advice, would be you do not need 13.8 A.F just to cool the engine.
Tweaking the CLB to 700 or 720 would still be enough to cool without being too rich which cruising! ( And that solution would allow C/L fueling to remain operational. )
That's my 2cents..

You may want to double check what the aftermarket is saying.
