What would I have to do?

Dr.:

Ignition 'timing' is controlled by the relationship of the position of the piston to when the spark occurs.

If the ignition spark occurs too soon (timing advanced) it can actually push against a piston traveling up the cylinder as it is compressing the fuel/air mixture. This causes detonation, lost power, much higher combustion temperatures and possible early internal engine part failures.

If the spark occurs too late, (timing retarded) the ignition of the fuel mixture occurs after the piston is traveling back down the cylinder. This is wasted energy, unburned fuel, high emissions, and lost power.

Generally, advancing the timing (to about 14 degrees) on a 5.0 engine gives you quicker 'throttle response' and possibly a 1/10 second et drop in most cases. No HP gain but a performance gain - for free. The best kind of mod.
