Help with Error Code

[VAUGHN1488]

I have only partial boost pressure,most of the air on the intake side is being expelled rather than inducted.
I have an error code of : P0472 Ex Bk
PRS S CIR LO IN

I am assuming that the P0472 Ex Bk is "exhaust block" I do not really know but what is the "PRS S CIR LO IN"??? These codes were taken off my SCT Tuner.

I will appreciate any help you guys could give me THANKS.

Kinda' sounds to me like a "hot air side' leak going to the intercooler. Checked your hose connections? May be the intercooler.

All my hose connections are good already have been through them...but thanks for the help.

Somebody will be along with code discussion. I was just taking a 'stab' at what it sounded like to me.
Oh yeah - you might want to post truck model, etc, That will help.

The truck is a 2005 6.0 Stroker...with an AFE stage2 intake, Magnaflow 4" turbo back exhaust,and a SCT tuner w/extreme street(now running the stock tune).
Tried to edit my original post with above information but it wouldn't let me change anything.Thanks for the heads-up Big Al and for the help too.

Bump again.

I guess nobody here knows what the code is...with all the members on this board I thought somebody would have the PC/ED manual.

I guess that I am going to have to spend $50.00 + shipping for the manual.

Thanks for the bumps Big Al

You're welcome. I have very good analyzer (Autoenginuity) coming, but don't have it yet. I maybe could help you out if I already had it.
