If you need more power for towing, why not just trade it for a diesel in a similar year range for roughly the premium of what the SC would cost?
I will say that it's typically not recommended to haul heavy loads for long distances with supercharged trucks, because the IATs will climb which will cause detonation and power loss. The tundra supercharger system was designed with increased towing capability in mind though. I towed quiet a bit with mine, but only a handful of times with really heavy loads. I pulled a 9K# trailer/skid steer combo all over the place no problem. Once I pulled a 12K# combo a short distance, but did experience some brake fade. With the heavy loads the towing acceleration was similar to the F250 V10 that I was doing most of my heavy towing with at that time.
I will say there have been some guys blow their engines. Almost all of these guys swapped pulleys and ran either a stock tune or a canned tune. I wouldn't swap a pulley without getting a custom tune and likely bigger injectors depending on the tuner's recs. At the time I sold mine there was only one guy who could custom tune them in the world and he was located in Dallas.
I toasted mine without boost.
