The TIMING TUNER box is awesome:bow:

Timing Tuner?? More info please!:)

Do a search for it as TIMING TUNER. Its also a nitrous controller box all in one. It plugs into a few sensors and the crankcase. You can mount it beside your air box and easily adjust timing with turn of a knob. Heres what it doe... advances timing, retards timing when nitrous is activated, built in window switch, and also if you have a superchager it gradually takes timing out rather than all at one time.

Mallory's Hyfire VI (part #685) is QUITE good. Look it up on jegs.
