I for one thought it’d be enough for me to turn off ASD. It doesn’t seem like I’ll be turning off ASD.

Now I have a full exhaust with mine but there is a definite noticeable difference (on a cold start and idle, in addition to driving under load). I cant compare because it was installed with and part of the Valvetronic exhaust.

It it is truly fully opened, there should also be a performance benefit, especially in sport/sport + modes.
