How much HP can I gain from upgrading my ignition system?

[SleeperD150]

Just wondering if it's worth upgrading my ignition system from stock and if so how much power would it give me? Any feedback is appreciated.

just the ignition, little to none. may run better so if you were under producing due to poor spark then it may bring you back up to 'normal'. but I don't think you'll get much additional power out of a stock 318 by going to a high po ignition.
