So I bought the Lund nGaugew/E85 and I had the stock headers and now I’m planning to go to these headers.I told my tuner that these headers require a custom tune and he told me that my 2017 Mustang GT doesn’t need another tune for the headers.Is he right?

Asked by: rocky71
Yes, he is correct. Because you already have a tune with them, their tuning is adaptive. If you did not already have a tune with them, you would need a tune. It's always good to notify your tuner of changes but if the calibrator tells you that the changes you are making to the vehicle do not require a retune, you need to trust them.

Why does it need to be tuned? 

Asked by: rocky71
Because you are changing the locations of the O2 sensors and the increased airflow of the high-flow catalytic converters. These two things will usually trip a check engine light when modified. Also, to make best use of the increase in flow these will provide, you will not see any big performance increases without having a custom tune as well.
