Hi, I have a gryphon and a cold air intake in the mail and have a question regarding if I should wait until my custom tunes come before i install the intake. I have a 2007 Ford F150 5.4.
I have a feeling I should wait for my custom tunes before I put in the intake which should compensate for any leanness.
I'll just use the canned tunes for now I think but I figured i'd ask here first
Thanks in advance!
