Excellent answers my friends! I truly do appreciate the "honest" feedback! In addition to your explanation of octane ratings, what would you recommend I run in my truck? 87 octane is definitely cheaper by far around here lately. With that being said, what should I do with my custom tunes? Change them over to 87 because there is not much difference or keep the 91 custom tunes because they are superior and worth the extra money to run the higher octane? And lastely, how much would it cost me to have the tunes changed over to 87 octane on both tunes if in fact you feel I should switch? Thanks in advance, you are awesome!!!!!!
