Does anyone know if I technically need to "re-tune" for an upgraded Valve body(IPT)?
And the car will still run fine on a step colder plugs for a bit without a re-tune too, wont it?

Looking at putting this in the car first if I can still drive around with it in, without hurting anything, before I completely tear it apart.
