What is the best / cheapest way to retard my ignition timing for ~10lbs of boost using a SAFC hack? Or can i get away without doing it for a while? I know of the whole msd ignition thing and it looks like the best way and it will geve me a better spark but i don't have the money for it right now (poor college student). I have also heard of modifying the dizzy, but i really don't know anything about it. any and all help appreciated.
