Contour Enthusiasts Group Archives Forums Modifications General Mods Apexi 8 point safc vs 12 point safc

I just read the SHM tuner and it said 400 rpm increments not 40, is it a typo on their part? Also how much are these things.
how hard is installation compared to the apexi?
I like the Apexi 12 point system, knock system, etc.

depends on pricing, I'm running rich now and need to fix it.
