started running 87 octane when I bought the truck and switched to 91 octane shortly after. started getting way better mpg and power with just higher octane. installed jet v-force plus and noticed only small changes in performance and barely any in mpg. if i was to do it again i would buy cold air intake and exhaust instead. only had it on the truck for a few days i hope it gets better.
