Does the Magnuson supercharger really help with low end torque?

I am thinking about buying a Magnuson supercharger if it actually helps with low end torque. I can’t stand the 6th gear to 5th gear downshifts on flat ground. I live in South MS, which is very flat, and I can not hold 6th gear on the highway at any speed. I have an OTT tune and it didn’t help the downshifting. My truck is stock besides the OTT tune. I’ve thought about selling the truck, but I don’t like any of the new trucks on the market today. Does a Magnsuon supercharger help with torque…
