08 Silverado new to tuning need help

[ahess0767]

I have had a remote tune done through a shop and I am having problems with both banks going lean and very rough running. I got the truck tuned because the initial problem was it wouldn't start. Now it's starts fine but runs bad. I did a cam swap 212/218 112lsa. Very moderate so I don't know why I am having these problems. Should have been an easy fix. But I know absolutely nothing about the tuning aspect. Have been reading a whole lot on this forum and I have been able to set up some graphs. But still having issues with tuning myself.

I will send my tune and scan file in a few. Having trouble loading to screen. First time
