Default Sct x4 tuner

Just trying to understand this tuner as to what it can do. It came with my car so I didn't buy it but I loaded the 93 octane tune on it which only thing I noticed different was the price at the pump. I saw you can do timing bumps but is the timing already bumped max on that setting?

Anyone doing something different with this without buying a tune?

Mods are full exhaust, Cai, 373 gears, throttle body.

Then it was probably already tuned for a 91-93 octane tune. I noticed
the difference right away from stock to the 93 octane tune, even with using
87 or 88 octane fuel, it still launches better. Just can't get on it due to
time pulls with 87,88 octane fuel, but it's better. I am also getting as high
as 28 MPG highway on 91 octane fuel with the tune, and new NGK G-Force
plugs.

You wanna test it, just go with the stock tune, run it, then go to the 93, you
will notice the difference.

I don't drive it enough I guess to notice it. I just think that engine wasn't powerful enough from the factory
