Driving home from work, my GXP had no boost. This has never happened before and no error codes light up. I turned it off and checked the hoses, everything seemed tight. I did get about 3 or 4 lbs of boost but then it went to 0.

Any ideas?

Duck1313:
Do you hear it spool up?

Deep-GXP:
Nice question Duck.

Chuck and Duck, this happened to me on the first tune that Lyndon gave me for the GMPP. My turbo STILL SPOOLED UP, but the DIC read 0. I went WOT 2 more times and the DIC PSI was still at 0 but the turbo still spooled and you can hear it's loud noise while accelerating and when letting go of the gas pedal. I have the Dejon Intake, so I can really hear it.

I flipped through the DIC until I came back to boost/psi and it worked fine after that.

I now have an updated tune from Westers. I can say without a doubt that this is the smoothest my car has ever ran. I see the psi go straight to 21, then it builds to 22, 23, then 24 as i go up the rpm range. My DIC has been working fine ever since installing the new tune. Actually the only time it happened was that one time and all i had to do was flip through the DIC until i got back to PSI.

I had this happen to me at the track, a hose came undone

Dark Tech is coming tonight, perhaps he can check your hoses. Did it feel like the power was gone?
