Unless you get your IAT2 under control it really won't matter on the stock tune. Also, unless you have a tune loaded that adds more timing for the added octane, I wouldn't bother.
Thanks, do you know how high can you go up in octane without a tune? I am guessing you would add the gas, pull the fuses and let it sit overnight?
