Weird noise after 4 speed install

Before adjusting the idle timing in the FiTech software I would throw a light on it and see what your distributor is installed at. I don't believe the FiTech allows your idle timing to be set lower than what the dizzy is stabbed in at. ( I could be wrong on that one though) Mine is stabbed in at 18 degrees, and I run 20 degrees at idle and 34 pretty much anywhere else, it works with my setup.
