Thanks in advance!
I was about to propose RaceChip to you.
But since you want burble, then you'll need a flashtune.
Just be careful with burble, it may damage your catalytic converter if you are too aggressive on it.
how? any proofs?
I don't have proof because all of my customers that using flash tune with custom burble are running catless.
But, there are complains about catalytic damages that is related to custom burble tunes.
My downpipe suppliers confirmed on that.
