i'm running a internal wastegate with a 10lb spring, i'm wanting to stay around 6ish. somebody told me that even with a boost controller i cant go below 10psi if i have a 10lb spring. you can only go higher with a boost controller. so would i need to get a 4lb spring and just turn up the boost from there

 

You got it!

But one problem, Normally you can't change Internal wastegate settings, if you want to go down, you have to lengthen you WG Arm(create LAG) or get a new wastegate.

 

or just the spring

 

no spring in internal wastegates that you can change buddy

 

You need to buy a new waste gate acuator. I got the Turbonetics one and it worked well.
