I recently bought this truck back in April and recently bought an AFM disabler (OBD port) which works amazing driving in V8 all the time. Curious to know if there even is a point of putting 93 in over 91. I’ve been doing both since not all gas stations have 93 but if it’s available I’ll always put 93. So far, can’t tell a difference in MPG. I still at least want to know if I should still stick to 94 no matter what. As far as tuning. Would it be pointless in buying one since it’s already at 93? Or should I still get a tuner to wake up the engine and add HP/TQ IF IT WILL DO THAT.
