I am switching my K&N air filter over to a JLT. Do I need to send it back to Brenspeed for a re-tune?

Give him a call and he will email you a tune, you will need one because the jlt intake has a larger dynameter tubing compaired to the k@n, if you don't retune you risk having some drive ability issues.

Yes you need a new tune. The k&n has a smaller maf housing so it can run on the stock tune. The jlt2 requires it own special tune.

If you bought it from him the send it to him for a retune, if you didn't then I suggest you buy a tune from ba ma chips.com because they will update the tune in the future for free instead of charging you for every update.
