I just checked and it’s coming from Vegas and ETA is Monday, so he definitely has some in stock. It was a very quick turnaround between order and shipping so I wonder if he’s lurking the forums and associated this post with my account. Either way, that’s good.

I also spent the money on a pressure leak tester so I’m going to pressurize the system and see if there’s a leak. I’m going to fix this damned problem if it’s the last thing I do.

Back after my initial post on Thursday. I was running low on boost, about 1-2 psi before I got the same DIV+/solenoid. It also just seemed to work better overall, with boost consistently going into throttle as well.

Okay, back from the track day (Took the Corvette) and an update. The DV+ did not fix the boost leak, and I tried to pressure test the system with a new boost leak test kit. The system wouldn't hold any pressure and would max out at 21PSI when applying 26PSI of pressure through the system. I couldn't keep it pressurized without adding air to the system, so something is definitely wrong. I also found what appears to be an oil leak in the turbo area so I think I may be looking at some sort of turbo problem. Frankly this is beyond my skillset now, the cheapo-fiesta is very quickly becoming the very-not-cheap fiesta. Oh and the slave is starting to go out as well so transmission has to drop as well.

How did you do the boost test? There are some spots that will leak boost that you have to plug in order to do it correctly. You connected the plug/compressor at the turbo inlet, or the compressor outlet/hot side charge pipe?
