@CSG Mike @Jackson Racing

With the required supporting mods, i.e. bigger injectors, fuel pump and custom tune, can this smaller pulley be run with 91 octane on occasion? Like on road trips where e85 is not available. 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?
