Hi, I am fairly new to tuning and have kept clear of changing anything other than VATS, 02, EGR, PE, and such until I can get some class time in. I have been working on GenIII's primarily with no issues, but I am currently working on a 2014 GMC Savanna 6.0. into a 66 Nova The problem I'm having is I unchecked SES and set to no error reported on P00B4, P0443, and P057C and I still get the MIL immediately after starting the engine along with the P1516. I have went back in to DTC's and changed the setting to "No MIL Light" and I get the same issue. I'm missing something but I can't figure it out. I have read and read trying to find something before posting this so please don't flame.

Thanks,
Michael
