Well, I just talk to Chris at tillman and he said that I will be ok running a 91 tune on 93 octane, just not a 93 tune on 91 octane. But like I said earlier I'll be getting a new tune as soon as I can. (waiting for the another sale at Tillman!!! )
Correct, we have 87, 91, and 93 available. You can run a higher octane than a vehicle (or a tune) is built for, but not a lower.
You do not want your timing to get ahead of combustion or you can damage your engine.
Well been here for a few weaks now and I love the better performance but with nearly no rain here theres alot more oil on the roads so hooking up on the street is different than colorado, the silver lining is it's easier to drift the turnabouts :hihi:
