Misfiring problem driving me nuts!

[Razi]

Get ready for a long read. Some info on the car: The engine is a turbocharged KA24DE, and my car is a '93 240sx .

-Issues:I've replaced the head gasket recently (It went well), and during the process I removed and blocked off the EGR doodads and I've replaced all the vacuum hoses as well, but I'm starting to question whether I routed a vacuum line or two into the wrong path...

--On Start UpWhen the engine starts up, the vacuum sits at around 20 until the idle drops below 1000, then the vacuum goes to 15 and hesitates. One reason why I'm worried I could have made a mistake in routing some of the vacuum hoses.My vacuum used to be at 20-23 during idle before all this.

If I unplug the electric vacuum valve controllers at the back of the cylinder head the vacuum does not change and stays at 15.

-Things I have done so far:-Did a boost leak test and fixed the leaks.-Fuel filter replaced-Fuel pressure is at 41 psi at idle.-Injector o-rings have been checked, and they are fine.-MAF sensor voltage fluctuates from 1.13 to 1.22 volts while idling. (Checked with consult cable and laptop)-TPS voltage is at .50 while idling. (Checked with consult program)-Timing at 21 degrees. (Checked with consult program)-Battery at 14.08 volts-Coolant temperature shown on the consult is about the same as the temp shown on my Autometer gauge. (So I'm guessing the ECU's coolant temp sensor is working properly).-The distributor, and everything on the distributor has been replaced a few weeks ago.-New knock sensor-New spark plug wires-New water temp sensor (For the gauge cluster, so I doubt that matters)-New O2 sensor (Voltage at .32-.33)-IACV has been cleaned few weeks ago.-All vacuum hoses have been replaced-New Deatschwerks 370cc injectors-Blocked off EGR

EndOne thing I would appreciate is if someone with a KA24DE on an engine stand could take detailed pictures of the vacuum hoses on the back of the engine and the back of the intake manifold.

Thanks for reading through this long post!
