Oh man this must be good Friday,that is one of the best suggestions no one ever came up with answer or easy fix.

I do not understand why the factory tach is off that much but it sure is,and my wake up call was watching the two together.

I do not know what happens as far as what is pulled either spark or fuel,but I think at that rpm you are hurting the valvetrain anyway,yeah I know cars leave on the 2-step all the time but they are only on the 2-step for .400 so no comparison there.
