cel 3100 after n20 map install and RBs

Can't figure it out.
I just got a new clutch installed so I haven't even been over 4krpms yet.
all I see in the forums is this code always attached with at least one other.code but no solution yet, that I saw.

3100 is just an error code that appears whenever limp mode is triggered. Are you getting a P3100 or H3100 and any other codes?

You will need to figure out what is causing the limp mode(3100) and fix that. There should be another code triggered at the same time. Most likely suspects are boost leaks, misfires or VANOS issues.

If you have Autoclear turned on then you will need to turn that off.

Do you have the setting in the interface changes if not it will cause code.

Problem solved, defective RB pcv valve, put the stock one back in and the car is running healthy again.
