to start its a 99 civic si with a vortech supercharger
started at -35 all across and took them all the way down to -50 at idle to see if it would go away, it never did.
Cold idle was about 1100....as the car warmed up the idle raised.

How long has this been installed for?

Any codes? The injectors are known good? Sputtering? Have you taken it on any pulls? How did it run?

How about the rest of those settings.

Well, I was referring to the other settings like in/out, sensor type and ---- like that. Are you 100% sure these are all correct?

Damn, your making it hard on me to help you out here.

Car select: 4 cyl and "/"(pointing up)
Sensor Type: Pressure(don't touch anything else here after you select pressure.
Sens. no: 06/06
DO NOT INITIALIZE(some people have done this thinking you had to in order to save the settings).
I like to set the Th-point to 74lo/75hi, but as long as they are close to each other it shouldn't matter.

So how are we looking now?

Everything is hooked up correct? Did you check? Double check? The grounds are hooked up right and the in and out are correct? What does it read for sensors? (ETC>Misc.>sensor check>)
