Well I put in two blue springs which according to the chart should bring in full adv at 3000. It had the two heavy springs in it before. I can't say that I noticed a big difference. It did not ping or buck at all even at low rpms. I am looking for a little more low end spunk. So I am going to try one blue and one silver spring to bring in full adv at 2500. Of course I don't stomp on it with the rpm too low. Thanks for everyones insight.
