Wow, what a plethora of codes and a common running issue.
Let me start out by asking who did the delete tune? We have run up to multiple programming issues from switching from CNG only to dual fuel or CNG to gasoline only, with a time period of running then the issue exactly as you described. Turns out to be a ECM/PCM programing issue.
Your codes need to be investigated by a capable technician. U1424 & P0641 can be related, the U1424 is the Trans Control Mod asking for more power or torque and getting none, the P0641 is a insufficient power for TCM request. P0193 is a Fuel Rail Pressure High code and can be the result of the easy route tuning, increase fuel pressure to increase fuel thus increase power. P0106 and P2016 are both manifold pressure codes whose sensors are all 5 volt supply and share a common ground or could be the result of the delete tune attempting to get more power by speeding up the turbo. Or you could have an intake manifold leak.
A good technician and a knowledgeable tuner could possibly figure this one out but with the delete you make things a whole lot more difficult for a technician or tuner or programmer who didn't do the original delete, as it is easy to download a factory program but with all the sensors missing from the delete,,,, well you get the idea.
