You will WANT a tune. Contact Uprev LLC. I lost power after my header install.
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?

I was one of the ones who did not have an increase in power "across the power band". I only noticed a slight increase in top end. Now......after Uprev tuned the truck it was a whole different story. Either way you are dropping some cash, but as brad suggested you dont have to go all out with the titanium's. I guess it just depends on what you are after and how much $$$$$$ you are willing to spend.
