Hey guys I have a FBO e92 on 30-40% ethanol.

The other day I was driving normal, went to give it some gas (didn't hit WOT) and the car went into the yellow limp mode. It said still Ok to drive so I just went home and pulled the logs. I have a flash so the JB4 is set to 0 and menu option 4 is set to 3. I pulled the codes and this came up:

3100 low boost mode engaged - CEL displayed
2EF7 characteristic diagram thermostat, controls

Any ideas?

I drove the car this morning and the light is gone and the car was fine. I didn't try and push it though just normal driving.

Any help is appreciated. Thanks! oh I have 40k miles and plugs are less then 3k on them.
