If i put a high performance intake and the not running as good should the computer should be reflashed
I might imagine you would need to ask this question from the maker of that “high performance intake”
I doubt asking this type of question and with so little details of this forum would give you what you want
Describe the high performance intake. Does it use air from outside the engine compartment, or does it suck air in from the engine compartment?
… and, does it utilize a “permanent” filter that you saturate with oil?
It’s not uncommon for a tune to required when you add an aftermarket CAI these days. Usually the CAI’s marketing material and/or the seller will mention it. Some do require a tune, some don’t.
