Hey everyone I have a question regarding unleaded race gas options for the 5.7 Hemi. I have a cam and have a tune set up for pump gas 93. I am plan on when I go to mexico or road race the car i plan to put some unleaded race gas into the tank to help with any detonation because i know that just cause it says 93 does not mean it is 93. So I have heard that the Sunoco 260 GT is good but i want to know about any other good unleaded race gas options. I know there wont be any performance gains since the car is tuned for 93, i would only be using the race gas to bring up the octane to help with any detonation and knock that may occur by using pump gas. Thanks everyone and appericate all the info.
