Submit a sat without writing that i'm happy with and a meh act with writing or no ACT with writing

I am looking to apply to schools for engineering. I have taken the sat and got a 1480 and also did subject sats( Physics-760, Math 2-790) but i skipped out on the writing section. However, I did do the writing section on the act and received a 30 composite score with 29-31 sub scores and a 9 on the essay portion. If the colleges I am looking to apply to, UVA and VTech engineering maybe more, do not require the essay should I only send my SAT score and subjects? Or should I also send my ACT scores?
