Hey guys i was looking in my SAFC looking for my 02 voltage but i went into the etc. menu, then to sensor type and then down to karmen and my car shut off, it won't start unless i use the gas and then it idles at 1100rpm and when i rev it up it wont go past 1600rpm.. wth did i do?? help me!!!

alright i went back into karmen and it runs normal now but something else is wrong with it because at idle my boost guage is at 20 when i rev it she jumps to 10 really fast then goes back down.. ahhhhhhhi hate this!!

Your boost gauge is 20psi at idle? Or is it 20 in/hg? If its in/hg then thats about right. I believe it should be around 18 at idle and 24 while decelerating.

I think i got it. It is at 20 when i first start it and if it sits and idles. If i rev it then it goes to 24. It's not at psi. what does the in/hg stand for? I'm sorry you have to bear with me i'm new to turbos. But anywho it seems fine now. All i did was went into the etc. then i selected karman and it shut down. then when i actually went back into karman and selected it then it started fine and ran fine. What exactly is that?
