GReddy Profec B

[Tsi]

I have had my profec for a couple of months i finnally got my tranny fixed and i fell that I want to turn the boost up.

MY question is what does the dots represent around the Low and High boost buttons so i know what i dial in before i hit it?

Thanks for any help.

Those dots don't neccessarily mean anything by way of representing psi increases.
Now having said that, When I adjust mine, they are close to one dot equaling 1psi. But I have seen a few others cars where it is maybe 3/4.

After adjusting monitor your boost gauge to ensure proper psi.

yeah the dots dont really mean much and can vary from setup to setup.. Just keep turning the knob up a little bit more and more on WOT runs and watch your boost gauge.

my only fear is over doing the internals, while i am so far away from home but gotty do what you gotty do


thanks bros

thats why you start it off with the knob all the way down and turn it up a lil bit at a time.

With my setup - my Profec B on Low all the way down is 14psi just to give you an idea. I believe all the way low (to the left) will set you to around the spring rate of the wastegate. It also depends on how you do your hoses. If i connect my wastegate directly to my pressure source it stays around 10-11psi which is about right for .7 bar spring. I need to try changing my hoses to the factory setup to see if I can have better adjustment on the dials.
