There was also a dyno run done to compare the two, and it showed the 93 making "slightly" more power and it appeared smoother, but it was a difference of power that likely wouldn't be noticed (just a few more HP across the entire curve), and also, dyno's are never perfect. Finally, it was said by tuner's that both the LLT and LFX had multiple octane tables.

So....that said. Nothing??? Not sure about that. Does using premium turn the car into a beast suddenly? No. But don't say it does "nothing".
