Is this normal?
If no threads are showing, then he needs to eliminate the backup nut located behind the turnbuckle. Then with the backup nut removed bottom the threaded tip of the actuator rod out inside the internally threaded turnbuckle tip. Now, thus bottomed out, count how many threads are visible behind the turnbuckle.
Remove the WGA assembly from the turbo. Clamp the actuator rod in a bench vise. Using a hacksaw, carefully cut four threads off the tip of the actuator rod. Reinstall the turnbuckle onto the threaded actuator rod w/o the backup nut. Thread the turnbuckle all the way down til it bottoms out. Reinstall actuator thus modded onto said turbo. Done.

Well Sparky, looks like fireman is right. To answer your question there is NO threads showing behind the lock nut. So I'm not preloaded?
And thanks for the help so far guys, I can't tell you how sick I am of not having boost.

Easiest fix would be to pull the actuator and elongate the mounting holes a little so the actuator is mounted further away from the wastegate, or you could put the rod in a vice and make the bends more acute to shorten it's reach.
It would be way easier to either cut 3-4 threads off the tip of the actuator rod, run a helper spring, or drill a hole further back along thr flat end of the turnbuckle. These mods don't alter the overall spatial relationship or affect the actuator rod's axial movement.
Easier still would be to get rid of the worn and wimpy stock WGA and just purchase the FP 18# HD actuator.

Well I took after sparkys advice and got a new fp 25 psi spring WGA, and am still at square one (still boosting really late). I even played with preloading and unpreloading it, no luck. I also had the car into nipn'tuck performance in Orem and they ran a smoke test to check for boost and exhaust leaks, and they found nothing. No leaks anywhere.
Where do I go from here guys, I have literally check everything I could possibly think of?
I have now had multiple people and a performance shop tell me that buschur could of ported the turbo and EM so much that it isn't spooling as fast as usual due to the wider space for exhaust gases, and it could possibly be a tune that fixes the problem? Does this have potential to be true?
I just always thought port work didn't ever require a tune!

It's not the porting.
Can you still move the wastegate flapper around like in the video? If you can then this is why your boosting late, The flapper should be pressed tight up against the wastegate port. If it is not and your wastegate is preloaded, then the wastegate flapper arm is bent or the hole in the turbine housing is worn out and your wastegate will never seal.
Did you have this problem before you sent your turbine housing out to be ported? It started as soon as you reinstalled the EM and turbine housing?
Are you sure the housing you got back from Buschur is the same one you sent?
Sounds like Buschur swapped your housing with a ported one which had a wastegate flapper problem that they were unaware of.
