So I tried to set my timing following the steps on the write up by hitman but the timing seems like at 15* is making it run way too retarded. So, I kept adjusting it 5* up at a time till it reached 30* where it ran perfectly and pulled hard till redline. Now, I vaguely remember reading somewhere that on some Timing guns the reading is inaccurate at the loop and should be doubled?? Is this why I'm needing to set my timing at 30*? Please help!! Thanks!

oh yeah, the CAS is exactly in the middle and reading at 30* if this helps..I'm using the black loop for the reading.
