Just to clarify on the mark motor IMRCs-The mark intake has two runners per cyl unlike the cobra so the IMRCs match up to that funny intake. It is too bad in a way because the mark one is metal and the default position is open.
If you delete the IMRCS on a cobra intake but leave the box plugged in and just remove the cables, wouldn't that stop a CEL? I guess you will need a tune anyway so may as well delete the function. Also, there will be different spark tables associated with the opening of the IMRCs in a cobra computer. If you have a GT, this does not apply.
