Okay to delete secondary air pump as long as I add cold start delete?

Hey guys. I want to delete my secondary air pump. I'll probably add a 3D printed block off circle to the intake boot. Is it okay to delete it as long as I have a cold start delete programmed in? Thanks!

You'll loose "secondary air" as an emission monitor, so if you are not emission testing your car I wouldn't see why not.
Do you have cats ?
And this is something to prob reach out to a tuner and get some input directly.

I did. Get some OEM block off plates for the rear of the heads as well.
