Modifies the Mass Air Flow Sensor signal to expected levels when EGR is blocked. Can also be used when a free flow exhaust system causes the ECM to set codes. Can be used on LLY and LBZ engines but not LB7. Please specify engine below.
NOTE: Finger stick installations are not the "end-all" solution for EGR Code removal. Some trucks won’t accept the finger sticks and will throw a DTC code. We highly recommend sending in your ECM so we re-flash it the appropriate way in order to have a permanent solution.
