Is a custom tune for diablo required for simple mods?>

If i just change exhaust and add a cold air kit would I need a custom tune for diablo predator? I was on www.runninwiththedevil.com and it said no..Is that right?

That is correct. You won't need a new tune. You won't even have to tweak your Performance Tune.
