New. Never got around to installing. Discontinued by MSD and had to seek out one before existing stock was sold out. Still has the twist ties on the wires and all mounting hardware, etc. The retail box has tape on it and torn so I'll rebox it before shipping. I think I paid just short of $400 for it, can't remember.
I run a Procharger with meth. I was going to use this to pull timing if anything went wrong with fuel, boost, meth, etc. I think Chris (gforce1320) runs one of these. Maybe he can chime in with experience.

Imagine the fun you ll have tuning your late-model ride with MSD s new Timing Twister! This sophisticated, user friendly control plugs into the stock wiring harness and gives you the ability to adjust the engine s timing with the twist of a dial.
The Timing Twister has four rotary dials that give you the ability to advance the timing curve, set up a step retard or even select a retard rate based on boost pressure. Control over the timing can help improve economy, improve performance and help tune the engine for other modifications.
The Timing Twister does not modify ignition timing at idle, but becomes active above 1,800 rpm. Once above that rpm, the entire timing curve can be advanced up to 9 in 1 increments. There is another setting for a wire-activated step retard, primarily designed for use with nitrous oxide. Another great feature is for the forced induction crowd. When used with the optional MAP sensor, you can easily dial in a retard that is based on boost pressure. Twist in .1 - 1.9 of timing per pound of boost to retard the timing up to 30

It is a great kit for nitrous. This was the cat's @$$ for quite some time. MSD quit making it. Dunno why. Heard b/c of corporate ownership changes w/ reduced product SKUs.
