    What happens if you remove the TPS and manually pivot it with a pocket screwdriver? (While it's still plugged in, of course.) Does it indicate 0% to 100% TPS Position?
    May God's grace bless you in the Lord Jesus Christ.

    Disconnect all throttle linkage and lift the Sniper up off the manifold/spacer or whatever combination you have. You may find your extra 25% there. It is sometimes hard to look down the top of a carb/Sniper and see that the throttle blades are opening all the way. I'd do that after you check the TPS per the above.

    Remember to cycle the key after you have turned the shaft all the way counter clockwise, this will reset the zero point for the ECU.

    Never hurts to make sure the plates are not hanging up on something.

    Here's an older thread and I'd check on the wiring diagram of the Sniper versus what's in the post. At the connector from the Sniper CPU you should get 5 volts measured between the supply and the sensor ground. If you have 5 volts there then you should get close to 100%. Note in the last post that the TPS was limited to 78%, which was found to be a stop in the linkage.
