    I've noticed a bit of a lag on my 2008 Chevy with the 4cyl/8cyl fuel saver. Is there a way to program it to lessen this?

    Have any of you done anything with this?

    i would check with the dealer and see if there is any tsbs on this and have them flash the ecm .with todays computer speed there should be no lag in the switch from 4cly to 8
