I thought I lost a MAF sensor as I threw the classic PSM/ABS code under WOT today...I blew my MAF about 3 weeks ago this way. Car went into limp mode and ran rough, stumbled if I stepped into the gas.

Swapped out the MAF for a new one, no difference, same codes, same issues. Tried taking out my Gembella ECU for stock, same problem. I am now getting 0 bar of boost, and I can hear a loud whoosh sound...I assume I popped or split a hose...what is the most likely hose to be the culprit? I'm running Vivid's AP Silicone hoses, Forge Diverters, FVD exhaust and EVO headers.

Thanks

 

I think you blew a hose as well, should be an easy fix

 

If I were a betting man I would say that the hoses that connect from the turbo outlet to the intercooler inlet may be the problem. Those sections are connected with a screw clamp and are the most likely ones to get loose or get a cut in them from overtightening the clamp. That is where one of my hoses came loose and where I would start the hunt. If that isn't the problem then start looking at the other connection points to see if they are loose.

Let me ask you this. Did you recently change the hoses to the Vivid AP hoses? If so, did you put the O-rings on the new hoses? I have those hoses and they didn't come with the O-rings. I forgot to put the O-rings from the stock hoses on the AP silicone hoses and got some crazy codes from the leaks, and my car went into limp mode. I went back and put the O-rings on the AP hoses and my codes went away. Either way, it definitely sounds like a hose problem. Good luck.

 

Agree w/previous posts. Own turbos long enough you will expereicen this.

That's what happened, but not on the screw clamp side, it blew off on the side with the wire clip, so I rebent the clip to be a bit tighter and wrestled the hose back on. Problem solved, thanks.
