N55 Code troubleshooting

hbaichan · 05-01-2018, 08:44 PM

So I recently installed a JB4 STG 2 with ff wires for my late e series n55. After installing i get these two codes 2C6F and 2C58. I uninstalled my jb4 and still get the two codes. Im completely lost as what it could be. A bad tmap sensor? a bad boost solenoid?
