Description
If you’re running a GM HEI distributor on the track or in high-boost applications, uncontrolled spark advance can cost you consistency, reliability, and power. The Fast Electronics Advance Lockout Kit locks your ignition timing at a fixed point, eliminating mechanical and vacuum advance variables so your tune stays true under all conditions. This is essential for forced induction engines, nitrous systems, and any build where repeatability matters.
