Hey there, I had something like this happen to my 2011 SS/RS about 2 years ago. I didn't get the "misfire" or anything like that, but I did get the code for the fuel pressure module malfunction. I thought the same, I'd check the fuel pressure regulator, but found out from my 2 sources, the tune shop that built my engine and the tech that works on my Camaro that these cars don't have a fuel pressure regulator, the pressure is controled by the fuel pump. So in finding that out and the fact that the car had 116k on it, they both said that it looks like the fuel pump is getting ready to take a dump!! The car was running kinda sluggishly, so I opted to swap out the old pump for a ZL1 pump and that made all the difference in the way the car ran. It was almost like it gained 50 more hp. lol. But I know it didn't. It was that the pressure was off that much to affect it. Good luck in your quest sir..
