Going to grab a Gunson colortune to help better tune my 66 after converting to the Weber 32/36 and Alpine Innovations manifold. Reading the most of the old threads it was generally recommend to grab two of the colortunes and put one on cyl #1 and the other on #4. That made sense when when trying to tune and sync the dual Strombergs, but is there any reason I would want two when using the Weber?
