Alright, I am installing a Ludespeed III kit with a Wolf 3D engine management system. My question, is it necessary to install a Vortech RRFPR? Also, Do i need a voltage clamp? I don't think I need either, especially the clamp but I may be wrong. Just checking.

 

IIRC, doesn't the stage III include a RRFPR? If you run the "stock" 6.6 psi, you should be able to get away without it, but be VERY observant of your timing advance table and injector duty cycle.
