Did you read the install manual at all? If you don't have it, you can get it on AEM's website.

But, to answer your question, try setting your SPr (wastegate spring pressure) to 11.5 and unless you've got a scramble boost switch wired, ignore the other two. To tune it, try setting your duty cycle to ~30, make a pull in 3rd gear and watch where your boost goes, then set the duty cycle up or down accordingly. Also, if you're in a cold climate like I am here in VT, you might have to turn down the duty cylce when the snow starts to fly

BTW, FUL is what the end of your gauge sweep is set to in PsI. I.E. - if you set it to 25 psi, the little LEDs will be all lit up around the gauge when you reach 25 psi. Try 25-30 PsI for that - looks pretty good to me.

Good luck!

 

I may try one out.

 

does anyone know how to set the "b" setting? i have my a set at 24psi but when i go to b and go to prg the settings are the same as A and if i change the spring pressure on b it changes on A..

 

The a and b settings only differ in their duty cycle

 

I'm willing to trade with anyone who has a tru boost gauge I have a greddy profec b spec2 and I'm not sure what to think about it maybe I'm just to dumb and don't really understand it?
