Truck feels much better after turning AFM and torque management off. Took a few days to really notice. Installed the 93 "hot tune" as well. Don't expect smoking burnouts or a Camero killer but the truck does feel better to drive. I recommend it just for the fact that you can turn off the factory restrictions and AFM, but for straight up power gains I recommend a custom tune. That's my next route.
