I installed the new Granatelli #1545 0 ohm ignition wires and they did the back to back dyno run. Hard to believe a simple ignition wire change could be such a nice jump in power. I know some are all for it and others are like NO WAY. But I had these on my C5 and C6 and in both cases the car made power and ran smoother. The C7 was smooth as silk before so no change there in terms of a better idle but the 13hp power gain even at 212 water temp is a nice gain and I am sold.
