Code P061B

Internal control module torque calculation performance

I did a pulley swap. To 2.5" installed the idler. Clean the air filter. Drive it for a bit. Not hard at all and it threw that code.
I haven't switched to colder spark plugs yet.
I'll do that tomorrow morning. But I've never seen this code before.
Any insight?

Thank you,

When I had that problem it was tune related

OP did you load a tune to support the pulley? I think others have done this w/o a tune but maybe it's the luck of the draw if you do or don't need a tune. You pull any data logs? Have you tried doing a KAM reset, maybe it will help the PCM to relearn the current config?

Good Luck!
