Umm yeahhh...

Have you ever pumped your own gas?

See those numbers that correlate to grades? 87, 89, 91, 93, etc.

i believe giac has a new fuzzy logic chip that allows u to use any octane bc it learns the gas thats in it.

You should not be using regular to begin with. It states so in the manual and on the inside of the fuel door. With a chip you REALLY should not be using plain regular.

Yes using low octane gas causes the engine to knock and decreased performance.

but if u had a fully built head and p&p u could use low octane. if ur engine never sees knock its better to use lower octane. although im sure ur not planning on spending that kind of money now r ya?
