So I was just looking online and there are apparently these plug and play “performance chips” that plug into the OBD port. They claim 30hp and 5mpg gains for under $100. To say I’m skeptical and leery is an understatement, but out of curiosity has anyone tried them?

I'd steer clear.

 

If you want to improve a VCM Honda/Acura, muzzle the VCM. Also, make sure the transmission has the latest software.
