Will these work on a 13 Chevy Impala .

I would verify that with manufacturers, directly.
I do believe so impalas did come with a 5.3 also

Did the tune wake it up on the 87 octane tune

Tbh I didn’t notice a huge difference.
I mainly bought it for the utility factor “multiple use options” instead of just the obd Afm disabler for $250.
Maybe a little bump in power nothing crazy though.
