So all you are doing is changing the direction of the T...

With this configuration, you will see less than spring pressure at the manifold. If you run it like this, you are taking your pressure source at the compressor, where the boost will always be highest, as this does not take in to account the pressure drop across the piping and intercooler. So if you put an 8psi spring in the gates, you may see 7psi at the manifold due to the 1psi drop across the system.

So, what you can do is run the boost source to the lower ports of the wastegates from the nipple on the driver side charge pipe (this is the port available in the kit). Then, instead of plugging the port on the compressor, you can run it to Port #1 of your solenoid, and then from Port #2 to the top half of the wastegates.

This configuration would work perfectly fine.

Well said Sasha exactly how I'm running my vacuum lines

My Innovate Scg-1 is set at the lowest duty cycle - but it's overboosting over 10 - 12 psi. Gain is set low.

I am thinking the solenoid is not working correctly - so I bought a Turbosmart manual boost controller.

Sasha or Jwick - I unhooked the line going to the top of the wastegates. Is it ok to run like this? for testing purposes...

So the Turbosmart manual has line from boost source underneath driver's intake - and into controller then out of controller to T'd side of both wastegates.

crossing my fingers...
