2350 cold weather MCF table adjustment

[SemiSweet]

My 2350 has been demandated by a reputable member on this forum. Alberta has been in a deep freeze lately -30 to -40 and I am constantly on the boost gauge trying to keep boost down under 30-33 psi due to the dense air. I have been doing some research on here trying to get a little more information on adjusting the MCF tables between 1500-1700rpm to limit the boost pressure possibly making a separate tune all together to load during the cold months.

I’m having to run a gear or two lower to keep boost in safe range and i cant run this thing at 60mph loaded (super bs) like this . It’s probably ok if I am in the driver seat but I will at some point have to let another guy drive my truck and they do not understand the damage they can do.

Any advice to adjusting these values? I have all the technology to perform these changes but I have personally not made adjustments to an individual tune.
