Just to let you know you cant socket obd2 ecus and have them pass inspection and they are also not flash tune-able SDP is right for right now a quick fix unplug the vac hose to the fpr just to see if it maintains the cel or clears it if it goes away buy an adjustable fuel pressure regulator that will be your fix if the cel continues look closer at bank 1 O2 sensor 1 thats the one closest to the motor its the one that controls the fuel table it maybe malfunctioning to where it wont throw a code but the voltage values are close to out of range other things that influence fuel air intake temp sensor check for vac leak or broken wires thats just a couple ideas to help
