Any ideas
Unless the reg is free flowing, it is very unlikely that switching between two appropriately tuned, balanced second stages will be the cause of change in your SAC rate, and especially not 30+% worse. I’m with @stepfen on this one.

Over next few days i could manually work. Out SAC and see if it correlates with Garmin calculation. I see thst if you use 80 imperial it defaults yo 12l air although i input 11.1 manually each time
