    How much can I gain if I tune my Hellcat to use VP's MS 109 racing fuel? I am told I could buy an HP tuner to switch back and forth between 93 oct and 109 oct tunes. 109 would be for the drag strip only. I am told if I tune for 109 and used 93 I would get lots of pings and poor performance, which makes sense. Mods include BWoody CAI and an ATI 10% overdrive pulley with a tune.

    Unless you a very good tuner and know how to tune a Hellcat you will be lost doing it yourself....................

    MKC Performance does my tuning. I would just switch back and forth for the fuel I am using. Thanks!
