Where does your turbo timer get is tacho signal?

Why I upgraded to the 9blade wheel when I ordered I dont know.... damn marketing ... . Believed the promise.
Well the turbo is on. I had left my fuel alone when I reinstalled my stock turbo so I had to be really careful about my EGTs. Starting off towing my boat like that would blow a huge cloud of black smoke till the turbo started spooling. I wanted to leave the fuel alone so I could see how the new turbo felt. I swapped over the wastegate and set it to where it was cracking at 22psi. I didn't want to set it so tight to where the electronic boost controller I have waiting to get installed was doing nothing. Before I was able to hit 22psi but at this setting I am hitting 15-18psi so that's a wastegate issue. Concerned that it was not enough preload to keep the flapper shut I disconnected the wastegate and she spun right up to 30psi but no difference in spool. Overall the spool feels slightly worse than before. Luke said this one would be moving more air since he increased the size of the inducer and to make up the spool for that he went to the 11+0 wheel.
Now people, me included, seem to focus on the psi and the spool and this one is close to stock in that reguard but it's not apples to apples since this one moves so much more air at the same boost level. My stock turbo set to 15psi would cruise at 100km/hr at around 10-12psi. This one sits at 6psi. I still wish I went with a GTurbo so I would know for sure it was my tune or my truck vs the engineering of the turbo but I'm going to do my best with this one. It did make a huge difference driving in the mountains. Tonight my friend is welding a bung in my downpipe for my wideband. I still need to finish my intake project so I can get my intercooler hooked up too.
Since I don't have my wideband installed I am still tuning by EGT but I have a question. When I floor it my EGTs go up but once the boost is up they start to come back down by hundreds of degrees. Since it's so short should I mostly ignore the spike and consider the settled number my real spec or is that something in the way I have my truck tuned?
@IanB
I have the star wheel backed out 70 clicks and then two turns (starting counting turns as clicks didn't do much). I think I still could go further and will start messing with it again
Edit:
Went out and did two more turns of the star wheel. I painted the rod but never pulled it back out to check. Wastegate still at 16psi. Not sure if I should bother trying to adjust preload or just work on getting my electronic boost controller hooked up. This star wheel adjustment made a big difference. EGTs are much more linear. I have never been able to add fuel via the main fuel screw but I tried it to where my idle went up to 1200rpms. My EGTs actually dropped doing that. I then tried to take some off boost fuel out by setting the cam from max to min since I added so much more fuel. My EGTs are way better than before and probably the best the truck has run so far.
When my pump was rebuilt the spring was changed by rebuilder to match the extra boost level. I think a stifferspring was fitted.Sounds like u need more on boost/ maxboost fueling . Try setting the compensator pin in the max position . Make sure it gets to the max position with your max boost pressure but not go into over boost protection . Shim the pin so it cannot travel from max fuel to overboost if you have to or grind/continue the taper further up the pin .
Get your max boost top end fuelling set then add or subtract fuel via the star wheel untill your happy with spoolup smoke and cruise temps . If you can't find a happy medium like that then you may need to back the pin position off or a custom ground pin or custom spring .
A good place to start is what ever your max boost is try to make your compensator pin achieve max travel at or a few psi before that Same psi point .
It's not always possible or desirable but it will give you a good starting point, depending on how your setup responds you may have to make compromises in some areas .
