Got P24B9 after supercharger install.
I installed the HKS supercharger clamped every hose replaced the fuel pump and upper injectors used the delicious tuning flex fuel kit, and I'm getting a P24B9 code which says "Evap system leak detection pump pressure sensor"
Car runs good, has no issues with fuel, doesn't get to rich or lean, only issue is the code keeps coming back. Shows up as a PDTC. I'm at a loss for what to check next? Has anyone had this code or have had a fix for it? Much appreciated! Update 3/28 - Got the Subaru Repair manual for the Car. Code actually means: The difference in pressure between the canister pressure sensor and manifold air pressure sensor is too big. So I ran through the "Factory Diagnosis" and got to the point where it said to replace the MAP sensor, so I put the factory MAP sensor back into the car and went back through the diagnosis, and It appears to be correct. I need to go through a few cycles to make sure this works, but it appears the tune was not scaled for the MAP sensor in the Kit or there is some sort of other issue with it.

is the flex kit Connect ed to evap or o2 sensor? also check the evap solenoid if it s ok or has cracks some where in the hoses
Also go back to your tuner and ask him about the code, could be related to the install of the flex kit, and maybe as easy as deactivate the DTC on the tune |

Yes, Had the Day off today so I took tested the solenoid to make sure it's holding vacuum and it does so perfectly. Put the Solenoid in and vacuum tested from the metal line and it held vacuum.
