If it is any help. I went through basically the same operation as you. Except my Silverado was an 09 and I removed the 5.3 and installed a 6.2. I had to put bigger 52lb fuel injectors because I still have an Edelebrock E-force supercharger to put on my 6.2. But yes for 6 months being a green tuner I have been tuning my 6.2 and it runs awesome. Much more power than the 5.3 with AFM. Once you get your license I might be able to help out on a program for your truck. I put a mild cam in mine with headers, and getting the balls up to install this supercharger. I don't know how much more torque it can get than what I have now. But once you get it tuned you will love it. Good luck
