Tune and Headers question

[Swarm]

so guys, I have a tune for a long time and I bought the BBK headers

so my question is do I need to contact BNR and ask them to change my tune to fit the new headers or do I just install the headers and re-tune the car with the same old tune?

how does this thing goes?


thanks in advance

you'll have to contact them and update them on your mods so that way they can send you a new tune file with the correct adjustments for the air to fuel ratio.
But also you don't have to update the tune, it would'nt really make much of a difference. from what i hear (correct me if i'm wrong) the car itself will adjust itself over time.

so its really up to you
