I just have it routed as diy's diagram shows

Wow yeah I totally missed putting two and two together. the boost controller should not be connected to the intake manifold. With an electric boost controller there's no downside to just taking the source off the compressor cover.

My turbo doesn't have a vacuum port on it.. Will I need to possibly buy a flange with a vacuum line in it or maybe drill/tap into the flange I have or something?

Go buy an NPT vacuum fitting and put it in your IC piping post IC! Cheapest of them all and most effective.

I have FM silicone one piece hose. I'm going to tap the turbo compressor outlet flange for a 1/8 npt fitting

Sounds like you have your mind made up. Although you could still do it with that interesting looking silicone fitting.

Aren't all these little purchases for the finishing touches so great?!?

I know the feeling. At least the big ones you're ready for. The little ones just add up and hit you hard.

It's not even the money so much... It's just that you have to wait for the part to arrive and I need it RIGHT MEOW! lol... Like my car is almost ready to be tuned (after I sort out this last turbo source fitting) and now I have to wait for a replacement wideband :-/

I'm going to make a gopro video of my Artech exhaust and post that tomorrow... I guess that'll keep me busy for an hour or so and then I'll go back to waiting for the UPS guy

Ugh... So nowhere to tap this flange. I just ordered one of those silicone taps from ATP.. Now I get to wait even longer to tune

Just have some patience and step away from the project for a while. No use stressing over something not in your control. Trust me, when I had to put projects on my car on hold for a couple days it helped me take a little mental break.

<<<@!1!@>>>

Yeah I will take a little break and concentrate on some work things for a couple days. Once my wideband arrives early this week I can take my time installing that and putting my interior back together. I still have my MS on the passenger floor so I would like to permanently install that and get the rest of my interior back together haha

Made an exhaust clip today (Crappy cell clip because I forgot my GoPro at home)

I think its rattling a little so I will have to put the car in the air to double check that

Something I tried doing lately is just work on it for like 15-30 minutes a day and no more. Keeps me interested and let's me also keep on top of work and school. Saw a really good video the other day about a guy who worked on his saab 15 minutes a day for 20 years and did a full frame off restoration.

Lol its tough to spend so little time working on the car when its so close to completion lol.

Especially when the car is sitting right outside my office door and it gets slow at work... I walk right out into the garage and start tinkering lol

Today I pulled up my boost control settings and table. Can anyone take a look and let me know if I should change anything?!?! I want to start out tuning it for low boost... say <10lbs. Should I change anything?

low boost more than 10lbs?

Sorry if I do not understand this correctly, but is it possible to JUST run wastegate pressure on a dual port? What is your spring rated for?

I meant Less than 10psi lol whoops!

My current wastegate springs are set for 10.60psi iirc **Edit** Its the red/green springs for 10.15psi

is each port on opposing sides of the plunger/diaphragm in the wastegate?

Maybe just loop the two barbs together, then run whatever spring pressure is. Get tuning a bit, then use EBC for faster ramp up when it's on the dyno?

If you wanted to run spring pressure you would connect the bottom port of an ebc to the intake tubing. What you described would basically not open until the exhaust gas pressure gets high enough to force the valve open, thats a lot of boost in the intake manifold.
