Spark plugs and bootmod3 stage 1 93 oct

My set up: Full bolt ons
Tires- 235s sq
Spark plugs: stock
Mileage: 25k

I'm going to be flashing to bootmod3 stage 1 (not going further than that).

Do I need better spark plugs? What happened? What exact type? How often do I replace them

Do I stick with stock? How often would I replace them?

Replaced my stock plugs (Bosch from ECS) at 50K before doing Stage 1. My mechanic told me no need to go colder for Stage 1. Some recommend it but I've noticed nothing and no codes. New Charge Pipe as well.

Thank you for the input! How long have you had the tune since then? Was the slight power bump noticeable/worth it?
