Again though, I only have less than a thousand miles on the thing thus far. I don't know if there is any kind of a break in on it or what but it still seems abnormally low. When I first got the magnaflow, I'll admit that I liked to hear that exhaust give a nice thrum and was a bit throttle heavy, but since then (I put it on RIGHT when I got the truck) I really drive it pretty mellow all in all and I'm still getting barely 12. I figured around town I could get around 14mpg or so but its just not happening. Are you getting 15-16 in town or on highway. What tire pressures do you run?


Also, should I be running 89 or 92 octane gas instead. I've just been running "pure" gas without ethanol in it at 87 octane since new and only filled up a few times now. I wouldn't imagine the higher octane would help much if at all as I'm not hearing any pinging or anything going on that could be gas related.
