The custom tune should be able to pull enough timing when on 91 octane? Or do I have to change my driving habits when on 91. No WOT or redline shifts? I think I understand that there is no point in running 91 with the HBP because so much timing has to be pulled but I'm just wondering would it be safe when I'm not near a e85 station? |
Yes you can, but I would recommend keeping it easy; don't redline, and avoid WOT.
Think of it as being similar to running 87 octane in a stock FRS. You technically *can*, but it's not ideal at all.
