Reduced Boost Pressure

[Josh George]

Hey everyone, so i'm in a little bit of an issue. Over the weekend I was doing some spirited driving, and at some random point, the car decided to go into limp mode. Code 120308 (Boost Pressure lower than expected) and Code 120408 (Reduced power mode). Pulled over to the side, checked connections, everything looked good, so I thought it was a fluke, reset the codes, and decided to try another spirited drive to see if it would come back, and it did. I noticed on the JB4 screen, I was getting absolutely zero boost at all after the codes came on. I don't really know what's wrong or what to check? Has anyone else had this issue before? If anyone has any answers that would be much appreciated. The only mods I have are a JB4, catless downpipe, FTP chargepipe, armaspeed intake.

Sounds like a boost leak, check that charge pipe closely

That's what I thought at first, and I checked it and it looks fine but it was also at night so maybe I'll do a more thorough check later today.

I ended up uninstalling and reinstalling both my intake and my chargepipe and the codes went away. I did notice that one of the hose clamps was loose before taking them off and that honestly could have been the issue but I redid it anyways. More than likely, your chargepipe is loose somewhere.
