So i have many fast friends who absolutely swear by these so i decided to get one for testing i got the pfc30s coil and hot wire from a buddy and plan to test back to back with a stocker.  I have heard at the track guy gaining up to a 10th simply with a coil swap i gotta bite on that and give it a try ill be running this on my hpr small reed drag bike with vp110 fuel. we will see what happen in the real world may even buy one myself.
