I just bought one for my STS set up can you guys offer some advice on what I should start my settings at?

GT 67 turbo, with tial wastegate 5lb spring but it actually works like a 3lb spring because boost reference comes from the turbo housing and it's like 3lbs at the manifold after all the plumbing and intercooler.

I want to run 5-7lbs boost, can you guys tell me what settings will get me close?

Thanks in advance, I have a hard time wrapping my head around boost controllers, in theory basic but in operation I get confused.

mine is set at duty cycle 72 and works out to be 10 lbs of boost. Just set the duty cycle low and slowly raise it.

what spring in your wastegate? And what did you set your wastegate cracker setting at?

I have a 6 lb spring in the wastegate. I had the spring crack setting set at 6 and was getting a little creep so I lowered it to 3 and it holds the boost better. I have found out setting the crack setting a little less than the actual spring works better.

OK I think I got it close, when you up the duty cycle it's a small range that you finally get adjustment of the boost setting. It's going to take a while to get used to seeing the led display with the numbers changing up and down all the time under boost. The boost is set at 7psi but the numbers are constantly changing 6.98 6.99 7.14 7.08 etc.
