clock positions you get ....psi i on burger motorsports website it says adjustable from 1.75psi over stock at the lowest setting and 2.74 at 50% and up to ~4.75psi at max setting but i dont see where it says where to adjust the dial to get the desired psi. thanks

You may just have to do the math yourself with 1.75psi being 50% (0) and 4.75psi being 100% (4). From 50% to 100%, every 10% increment should be approximately 0.6 psi. So overall, 50% (default) will be 1.75 over stock, then every 10% till you get to 100% should add about 0.6 psi.

That would be my best guess in 2 minutes.

No prob. I thought 50% was the lowest setting.
