I ordered and installed the dual relief valve to fool the MAP sensor while the wastegate is disconnected, but twice in the last 3 days, it has still thrown the SES light, both times it was the P1249 code. According to the boost gauge, the truck is hitting a max of 21 PSI, the boost gauge is connected to the AIH. So I have no idea what the problem could be, it would seem that the relief valve is not doing it's job. Thats the only thing that would give the code, there is currently not a chip/programmer installed.
