No idea to be honest as the car is not tuned.

Main reason I removed the MST intake is because I started getting a strange misfire at idle. Reverting to the stock box removed it completely. It is possible that using different style intake requires a tune?

From the s550 mustang world if you changed the intake you needed a tune. Not sure if the same applies for our cars.
