Hi guys. My g40 has a gt dissy on. All i did was put it in bolted it up and carryed in driving. I have since gone to time it up properly using autodata it says put the gun on 6 and rev to 2-2.5k revs but i move the dissy to get it to somewhere near the marks it runs really bad and then when the revs are applied the timing marks just dissaper. Help please
