Code P2187

P2187

Something about my bank running lean at idle.

Im assuming it has something to do with the DP i have on that isnt tuned for yet. Correct?

ya i just had it cleared, it was limiting my boost to 12, and i was on a two hour drive each way so that sucked.

I have this code and p013a. It's not making more then 10lbs of boost and if I take off gently it will jerk a couple times like a miss (not drivetrain lash either) then it seems to run normal besides not making enough boost. Idk what the deal is
