I've been reading up on the P2261 code and there's a TON of info out there from deleting the vacuum tank to bad hoses.

I replaced the stock diverter valve due to a tear in it a few years back with the forge version. I am going to check all the hoses and rebuild the forge and lube it tonight.

Does anyone have the part numbers for the solenoid that is on the turbo itself and the one towards the front of the engine? I also want to replace the vacuum tank and I suspect is has a leak but I cannot find the part number. Thanks in advance. I'll take some pictures when I am done working today and post them.

12633355 is what your looking for I think. That's the boost control solenoid on the intake manifold. The boost actuator solenoid on the turbo I replaced with the one at full-race.com it's the same one on the zfr turbo item number 179425
