I bought a Ramchargers Timing Tuner for my No2 install, but will no longer need it due to a nitrous dyno tune. The timing tuner is brand new, never installed. Works for N/A and power adder vehicles. You can advance your timing for N/A driving, and have instant timing retard when you No2 arming switch is armed. You get the best of both worlds with this box. It also has a activation delay and a window switch built in. This is the add from there site:

"The Timing Tuner is a device that is installed on LS1 and derivative engine equipped vehicles for adjusting the spark advance ‘timing’ to extract improved engine performance. The unit installs ‘in-line’ with the crankshaft sensor wiring and alters the signal that is received by the PCM (Powertrain Control Module, ‘engine computer’). By shifting the crankshaft signal ahead or behind in time the spark timing in the engine is changed.

The Timing Tuner is used to adjust the Spark Advance to improve engine response and power. Assuming sufficient octane fuel is used, most production engines will make more power with a few more degrees of spark advance. However when Nitrous Oxide or superchargers/turbochargers are used to raise horsepower the spark advance must be reduced (retarded) to prevent detonation. Detonation (pinging, spark knocking) is very destructive and is to be avoided. Always run high enough octane fuel for the power levels desired.

The Timing Tuner also has a Nitrous Oxide (N2O) control feature. The unit features activation delay, timing retard, and activation controls based on RPM. The setup can be optimized for non-N2O driving and when the trigger wire is energized the secondary settings are activated. This ensures the optimum setting is always available both with and without N2O.

I'm looking for $200 shipped for this brand new timing tuner. Thanks, Jason
