Using brake spray, flush out these two hoses and the solenoid valve (but not the ALDA!). The valve should be passing between the two ports the hoses connect to. The upper port and the lower port connect when the solenoid energizes. This is the overboost solenoid that dumps your ALDA pressure signal to atmosphere when too much boost pressure is detected by the pressure switch on the manifold next to the hose port.

Also remove the port from the IM and clean it out too.

Make sure the hoses are tightly clamped. If these hoses are leaking or blocked then your ALDA will not get the boost pressure signal. This signal tells the IP to increase your fuel supply to match the extra air being delivered by your turbo. This allows the engine to produce maximum power.
I'll play around with it a bit tonight before my trip. Any rubber vacuum tube I can find is going to be replaced tonight.

All in all, who knows, it may just be as simple as cleaning out decades of grime lol

Glow plugs are brand new and all ohm out correctly. The miss I'm referring to, lasts less than 5 seconds. It's been really chilly here in Chicago the past few days, I'm not all too worried how the car starts. All the OM603's I've had did the same thing. I've got a spare set handy if that's the case though.
