Removing the Secondary Plates (Butterflies)

[tdragger]

The check engine light only comes on if you remove the connection to the stepper motor and linkages.

Just removing the secondary plates will not cause the check engine light to come on.

The rods that the plates were connected to will still turn as normal so the computer still thinks the secondaries are there.

If that's all you are doing with the intake and exhaust right now you should be fine. Aslo as Lester suggested the 12 min tune would be a good idea since you are technically making an intake change.

when i install the pcm do i need to install the o2 eliminator too, and i do not see a pcm tune for k&n plus tors with cat bypass what to do thanks john.
