Need some input here. I’ve recently replaced both my ssv and ssv solenoid and even redid the vacuum lines between them. However when I drive the car and at wot the car is very sluggish from 4/5k-6.5k exactly and then takes off and drives like normal from there. This made me to look under the hood and had a friend rev the engine and noticed the ssv wasn’t opening what so ever and I’ve tested to make sure the ssv was opening properly with a vaccum pump just to make sure the part wasn’t defected also and swapped around the solenoid and nothing has worked. What could possibly be going on as I also have no cel codes

Try this : run the engine for 30 seconds at idle , turn it off , wait 1 min , then watch the ssv while someone turns the ignition on then off.
The ssv should open as ignition is switched off then close a few seconds later.
This tests the solenoid,the actuator and also the vacuum tank for leaks.

If solenoid and actuator work while engine is running but not during the above test ...it's a vacuum leak.

Also : again after 1 min, reach under the intake manifold and pull off the hose that goes to the vacuum tank ... you should hear a sucking noise as hose is removed. No noise ...no good !

Welp after trying what you said I realized none of my solenoids were working and then I realized that the apv is what kicked on at 6500 not the VDI as I had originally thought explaining my performance at that power range. I then proceeded to eBay to try and find new oil filler necks thinking my vacuum chamber was what was broken then finally found out the their was a small vaccum line leading from the back of the chamber to the bottom of the upper intake manifold and after looking at mine I realized my line was unplugged and after plugging it back in voila the car ran perfectly...🤦*♂️🤦*♂️🤦*♂️.
