Here is the code possible causes , this is right out of the service manual

Failure to follow these instructions may result in personal injury. This pinpoint test is intended to diagnose the following: electronic throttle body ( ETB) (9F991) electronic throttle body throttle position sensor ( ETBTPS) (9E928) harness circuits: ETCRTN , ETCREF , TP , TP1 , TP2 , TACM+ , and TACM- PCM (12A650)

I also found a P2135 while thumbing through pics.
So it sounds like a new TB or can I replace parts on the whipple 132mm?
Thanks

I had a p2138 which is similar to the codes you were getting about a month back. Kept popping up over and over. I disconnected my bap and haven't had the code return yet. Been 3 weeks with no codes and no bap.

I am confused as to why Throttle body electronics codes are related to your Boost a Pump?

I thought it was pedal related and that’s where the BAP ties in, at the pedal.

Ah got it. I never used a BAP, went straight to the return fuel system.

Lund tune. Don't think the tune is part of the issue though.

Can you not put the BAP on constant or make it activate on boost? Seems like the pedal sensor is causing a problem.
