Anyone messed about with the ATP PSI adjustment, and if so, any ballpark method to +/- PSI sort of reliably prior to taking out on road for testing? I am guessing 'actuator' arm length change and pop off need adjusting.... rough how much adjustment per PSI?

Thanks.

Harry gave the the scoop today. About one full turn of the nut, closing it towards teh body of the 'actuator' will make the change of say from 6 to 7 or 8. I was at 6. Did the full turn and now the PIS is 7.

Even with such a small change, I can feel the acceleration difference!

This is my baby.... Courage to go to 8?

Hey JDC how about a bigger pic of your avatar, it looks awesome.

Thank you! I will have to go back to my original bike and engine composite (photoshop) work to find it. I will check that stuff late this week.

Quick update... slowly adding turns to up PSI. Reached 8 PSI in lower gears and 7's in upper 5/6 fulll boost by 7 K. Last turn was a full one after a full one and then two halfs. (three turns from "OEM" setting) So the actuator can control it some, though feels a little less precise/accurate. Will now dial down 1/2 turn and that outta be about 'sweet'.

I can see the reason for a wastegate.
