I been running mine for about 10k miles. It runs great but I only get 7.5-9mpg and dont really understand how the best way to set up the parameters for best efficiency is. Maybe I’m already there, but it seems I should be getting better. I just dont have the know on what to set or why. Maybe I just don’t understand the effects of 30” tires,4bbl intake, and performer cams impact on mpg. Not a lot of info out there for AMC360 but maybe we can share and figure out the best base settings for our rigs so I can go from there.

That’s one minute at idle.

I'm running it and very happy with it. Sounds like I have a similar set up as you. edlebrock 4bbl intake, performer cam, stock heads and exhaust.

I have stock wheels and suspension and get about 10.5 to 11mpg street/highway combined. I would be really surprised if you could get a whole lot better MPG with tuning- considering the weight of the SJ and a 3 speed transmission. Add the drag of big tires and your probably getting the best you can get with 7.5-9.
