Zlow28 is on a distinguished road

i could be wrong but the only difference between 91 and 93 etc tune, is the timing. I think its like 2 degrees difference between the two. So yeah, if you use the 91 tune, then use 91 octane, and so forth. Predator has a forum and theres tons of info there in case this didnt help.
