Predator programming question for 2004 H2

[Marcmedic]

Used to live in Albuquerque a few years ago. Had a sportbike that only ran well on premium unleaded. I added octane booster for a while and then decided to skip it and see how it did on the 90 octane stuff with no additive. No difference. I don't know if being at over 5000 feet has anything to do with it. Some of the guys in Colorado may have some more insight into this but I believe that you will be fine. Obviously if the engine starts knocking some octane booster would be required. I have the predator program installed and have no problems. I messed around with the 87 vs 91 octane tunes and the 91 octane tune is much better. You can always go to the diablosport website and ask a question and get an answer straight from the manufacturer.
