Hi, my question is, what do you guys/gals use for a management system on your 2.4L? and if it's a piggy pack, how are you setting the timing?, 2.4L are coil packs, and as far as i know you usually retard your timing a few. Any help would be great . thanks

Ignition timing doesn't depend on the ignition type. It depends on cylinder pressure, which you are increasing when you switch to a forced induction system. For a stock engine with a turbo added, you can generally leave the stock timing alone when you're in non-boost situations but you want to begin to reduce timing as boost increases. To do this you'll need a controller which can measure manifold pressure at least to the level of boost you're running, and rpm, at a minimum.
