Question level 3
The programmer says level 3 is 93 octane, the manual says 91 octane. Can we use either? I would like to try level 3 but all we have around here is 91 octane.
Also, while I am waiting for my custom tunes, what would give me better mpg, running 91 octane with stock intake or running level 2 with my Volant CAI? Just curious if anyone has tried it. I will eventually try them both but since I just received the gryphon today and I will be driving to see my folks this weekend (900 mile round trip). I was wondering which one would give me the best mpg since I won't have time to test them both out before the trip.
