I know some say theyre not necessary, but I cant find a good answer anywhere, and the last thing i want to do is launch my trans or melt a piston.

only thing i really do is change the iac flow per step in the bin

I ran one when I had my car. Did it work? No clue. The car ran smooth once everything was installed and I did a MAF tune.

I do not have one, and I also do not have the IAC step deal done in my car. it has a surging idle a lot of the time. not sure if it is related or not.

It did start after I installed the N* though.

I see that table in tiny tuner, what exactly did you change?

I see that table in tiny tuner, what exactly did you change?

i increased the value by the same % as the difference of the area of 10mm round OEM iac pintle and the 12mm round N* iac pintle (pumpkinPIE R^2)

also did it for the 14mm iac used on the 90mm LSx TB on the whippledRiv

for any given iac "step" position delta, the larger iac will flow more

Back in the day people used to just lower the threshold at which PE kicked in. If you already have a tuner why not just do that?
