Should I submit a 1480 to CMU?

I am an International Student from Singapore with pretty good ECs, 3.76 UW, 155 for DET (gotta submit one for CMU). I have a 1480 SAT rn, and idk if I want to submit it since it's low compared to their averages. My advisors are telling me to because I am an international student but idk if this would worsen or better my odds. I plan to apply ED as an ECE major. I also think I will take another SAT to better my score for other applications, will I be able to send a better score in if I have already submitted my app?
