If all you have are G3's, you are fine. By themselves, they are not going to affect A/F much. If you have full bolt-ons (test pipes more than anything else with other mods), you should consider it. None of the above should lean your car out to the point you would have serious detonation, but your mods would be much more effective with a tune.
