Hey guys so I have a jb4 tuned n55 and recently it's been throwing the code 2C90 I kept clearing it as I read that it is normal with the jb but now I notijb4 there are random times where my car builds no boost then the check engine light comes on with that code, then when you drive it for a bit Without clearing codes the code goes away then boost comes back. It happens at random, was wondering if anyone has this problem or if it's just a common jb4 issue.

Sorry I'm new what do you mean by a log?

I should also add that when I step on it and then come to a stop white smoke pours out the rear

Use your JB USB cable and pull some logs from the software and device.

Do you have the USB coming out your glovebox?
