Default ABC and utec

I just a quick and easy question for everyone. I'm planning on running the stage one map on the turbo xs website and was wondering what to do with the srew on top of the ABC valve head. The directions from turbo xs don't seem to say anything about it. I imagen this srew has to do with adjusting the amount of pressure. Well thanks for the help. Also I should not that this is a used utec and therefore I need to know where the srew should be at for a stage one set up. Thanks again.

read the UTEC manual. It's explained in there.

It's a bleed screw, use it to reach your proper boost targets if your boost map does not reach there.

the abc is just that, an auxiliary boost controller, u will use the boost maps in your utec for the initial tuning your boost curve, then u will adjust the abc to make ur boost peak where you would like it to.
example:: u set ur boost curve how u would like it, and u do a demo run, u come to find out that ur running 1 psi too much boost, so instead of changing the whole map in the utec, simply adjust the abc about half a turn closed
iirc: clockwise closes meaning less boost
counter-clockwise opens which means more boost

OK so would the stage 1 map be capable of boosting the 16 psi mentioned in the manual by just tuning the ABC?

u do not "tune" your abc, u tune ur UTEC, the abc is there for fine adjustment
the UTEC is the primary boost control, the abc is just what it stands for the auxilary boost controller.
use ur UTEC to tune to roughly 16psi, then use the abc for fine adjustment.
i.e. you are boosting 15, use the abc to bump it up 1psi. do not use it as a manual boost controller

Also, if you've ever run a MBC, it's possible that your SBS has gone bad, so the ABC acts as a way to crank up and turn down your boost, your UTEC allows you to adapt your fuel maps and such to adjust accordingly.
