Thread: i dont get it?

ok, im on overkills site and im looking at their PCM for my 99' GT, i noticed some options but there isnt anywhere to choose the options, it just asks me what year and car i have, wouldnt i want that PCM tune based on my mods?
how would i let overkill know what mods to tune my car for? and not just a generic tune. it said to provide a list so should i just email it?, i mean i really dont have much done, just an exaust and a wizard...
