Highly recommend the Magnuson through BB Performance, SC plus the tune. I have a '12 Yukon Denali with 40K miles on that combo. Upgraded the belt, went with 10psi undersized pulley, went to a cooler plug and just recently upgraded the inter-cooler reservoir as the plastic threads on the original stripped on the container itself. Been rock solid reliable. Even though factory exhaust is great on the 6.2, I upgraded to headers and the Corsa Sport and it is mellow until you get on it and then it roars. As far as transmission protection, if you run it hard in the summer like I do, I upgraded the tiny factory transmission cooler to the biggest aftermarket cooler I could get and my trans temps never get high enough to be concerned with.
BB Performance is very responsive and has adjusted the tune for me several times since. Towing on hills is fun as the truck many times with engage the supercharger instead of downshifting.
