Depends on what mods you have, if you are decently modded I would say a custom tune is in order. Contact Hemi Fever and he can set you up or there is a few more tuners on here if you search for them. If you are just looking for a quick tune type deal, hit up a bully dog tuner for box tunes that are pre loaded. or a to of people are starting to use EFI live but thats a bit pricier from what i hear
