I'm getting a custom tune this week. I only have headers and an intake at this time but new mods are being added weekly and next is a NX kit. So my question is, do I have to get two custom tunes one for NA and one for bottle and change the tune between the two throughout the night depending on how I want to run?
There are a dozen other similar questions but to sum it up, how do you run nitrous if you have a custom tune on motor.
Ps: please be as detailed as possible and talk like you are explaining it to a 5 year old
