BOOSTane Shot Octane Booster (10 Pack)

I have a 2019 Kia stinger with a jb4 tuner. Before adding boostane, the ecu was pulling 4.5ish degrees of timing out of each cylinder in peak boost.With the boostane, it’s not pulling any timing, and I can even run the map for e30, an ethanol blend, without experiencing any timing deviations!
