turbosol18

so im finally getting my del sol turbo dyno tuned!!

i got everything i need and i think im ready but i got one problem. I connected my manual turboxs boost controller and i cant raise boost?

I got the 6psi spring and using a tial 38mm wastegate. Below is a diagram of how i have my vacc lines hooked up



I will unscrew the small bolt inside the boost controller and boost wont go up it will stay at 6psi Any advise why or what im doing wrong? Im hoping to get this problem solved before i go tuning.

Also im open to tips for tuning, anything i should get or bring let me know
Thanks

Edit:

How many turns have you given it before trying to raise the boost? Typically it will take about 2-3 turns on the SBC before you'll start increasing your boost.

i thought i could either get source from the turbo itsself or the Intake manifold?

Well anyways where do i have to hook up the vacuum source?

i tried turning it and turing it and doesnt raise boost stays the same...just to make sure im doing it right, to raise boost you untighten the screw right?

At least thats what the boost controller its self says

I think you have the lines backwards.

anyone know the correct way to connect it? I thought i had it right but boost wont go up?? anyways ive searched but cant find any pics or diagrams

The nipple pointing down on the BC should go to the side port of the WG. The side nipple on the BC should go to the compressor housing.

Yours is backwards... just switch the lines on the BC.
