FBO Curve And Limiter Kit

I have that setup in my car. It makes it very easy to recurve the distributor. I think my current setting is ten degrees allowed by the FBO limiter and one silver spring and one stock spring. 20 degrees initial and I'm all in by 2800 RPM. With that setup I'm still at 35 total with no VA. I have tried several combinations and I will be changing jets and PV again soon and will have to reset slot sync but I am getting very close to tuning nirvana. Wideband helps immensely!
