OK so my CTS has told me I have a few more DTC's that I haven't had in the past. Recently my mods have been intake and exhaust and turbo inlet tube but, that was 4 months ago and I haven't looked at DTC's since before deployment back in March of 13. Im wondering how to properly make them go away without dealers help lol. Any suggestions or solutions are greatly appreciated
codes as follows

P0101=MAF sensor performance circuit A
P0236= turbo boost sensor A circuit
P0380=Glow plug heater circuit A (which Ive had for about two years)
P0540=Intake air heater A circuit
P1404= EGR ???
U1800=TCM??
