    Im new here so bear with me...So I just installed the Grimmspeed stealth box intake on my 2020 wrx. I thought the E-tune would come within a couple of days but they're backed up. Is it ok to drive without a tune if I stay out of boost? I don't really want to reinstall stock intake if I don't...
