04 M6 mod's need programming?
Looking to make the following mod's to my 04 M6:
Blackwing
Supermaxx System (including X-pipe)
Magnaflow cat back exhaust
My question is, do I need to have the cars computer reprogrammed based on these mod's or will it adapt on its own?
Thanks for your input

A good tune is money well spent unless you have more mods you're going to put on in the near future. In that case, you're better off waiting until then to do the tune so you don't waste money doing it twice. A lot of folks after header installs have had fuel mix problems, too rich/lean.It's probably optimal to wait until you stockpile a good majority of your mods and then do the install/tune together. I personally know very few people with that kind of patience or willpower! I sure don't have it.
