Just to be safe, I would. Some people run very lean with headers, some a little, so its sort of the luck. If you get just an intake, you won't run lean at all.mbouey90 said:
do i need a new tune?
My 04 titan has cracked manifolds and the dealer wont do anything (over on miles) so I have to get some headers, but I have read on here that if I do headers and a cold air intake the truck will run lean and I would have to get tuned. Is this true?
