I don't know you from Adam, but, I can see what kind of pride and the amount of time you put into your equipment, with that said. dump the mag, i have tried every ignition out there and 1 is head and shoulders above the rest. call Lonnie Morris and have him build you a complete ign. I saw instant gains (even noticeable without speedo/tach)I have been dealing with these motors for over 20 years and its the best thing I've ever done. Bryan Tharp 505-306-4909
