Ok first follow pic below to make a jumper wire. Warm your truck up and then install jumper as pictured. Now check timing should be 10 degrees, if not adjust to make it 10 btdc. Now turn off the truck and remove the jumper wire. Timing should now read 8 degrees and may change as the computer will now have control of adjusting the timing as needed. Let me know how it goes.
