91 Octane vs. 93 Octane with Chip Question - Urgent / On Road Trip!
#11
You'll be fine with a quality 91 octane
Under hot days repeated boost you might exceed the timing pull, but honestly 2 octane pts isnt going to do anything, except run less than efficiently
#14
That is fine for 91 found in the midwest and east coast
but 91 here on the west coast is more like 8 points worse then EC 93 octane. He will want to change over to a 91 octane chip once he gets to CA.

Yeah, just not a good idea... get the 91 OCT chip... your problem is the wrong plugs though...
get a copper core plug... you have to change them more often but they dissipate heat well and help to avoid predetonation. Make sure the gap is correct.
Although, I ran mine for 15K once... no probs.
