Got a weird problem as of late, happened on 2 Camaro's 13 and 14. After tuning the reduced engine power came up on the DIC but no codes. Car doesn't go into limp mode it drives fine normal and wot but reduced engine power keeps coming up intermittently. Again no codes and it will pretty much come on with the car idling. The 13 was just a bolt on header tune and I finally got it to go away but I don't know how. I basically rewrote the tune but made only change at a time until it was back to its modified tune. It's a just weird issue. Anybody run into this?

TIA!
