fuel octane

  1. H

    is there any way to check the octane rating of gas?

    I have a 2014 gt with about 6k miles on it. Im running an aed tune, o/r x, 1 piece drive shaft, airaid cai, and drs. I contacted shaun about getting a tune for nitrous. He told me based on my previous logs i would be pushing it with a 50 shot due to fuel quility. He said he would not do a tune...
