What Mpgs are you getting? I'm getting 12.2 with 35s and I can't imagine getting worse. U may not be as bad as others lol.
Cheapest way to get better mpg is cut weight. U have a hardtop? Put on ur softie or go door less lol. Maybe sacrifice ride quality by airing your tires up more too
Truthfully like others stated, spending money to save doesn't make a lot of sense. .depending on cost. Put stock bumpers back on, take off winch, etc. it's expensive to look cool unfortunately
And throttle spacers is snake oil

37" mtr/k s weight as much as the Jeep 
that is probably your biggest downfall in mpg. The procal adjusts speedo but doesnt change shift points. May want to sell it and try a superchips.

Lol. Seriously, with that combo, not much you can do that will improve the economy much. A tuner would be a good choice, and a free flowing air filter and exhaust will help some, but not much. Changing driving style will help as well, but doing all these things might add a mpg or 2..

Change your driving style and you will see the biggest improvement. My Jeep with the 3.8l, 4.10's, custom exhaust (sub $100), hypertech tuner, and K&N drop-in (I bought it for longevity, not performance) averages 16.9mpg on 37's with mostly city driving. Granted, that average is with no A/C. If I run A/C im in the low 14-15 range.
And yes, my dash calculator is pretty accurate.

So you are looking to pick up mpg's regardless of roi? If it takes 10 or 15 years to pay for itself in gas savings, that's cool?
Just an opinion, but change your driving style, or drop to smaller AT tires to increase mpg. Add performance components to increase power, any extra mpg they might give is a bonus.
