Any Jeep Owners on here with any MPG success stories??

[95CHERJUST]

I have a 95 jeep cherokee 2 door XJ auto 4x4 i6 4.0

I have done the following, any ideas for more FE or mpg success stories that would help me.

-Stan Meyer Replica HHO Hydrogen Cell all 316 stainless steel, puts out almost 2.0LPM, running at 10amps 150 degrees, b&m cooler too.
-Map and 02 enhancer to lean the jeep out since adding hho.
-Transmission cooler so Trans runs as cool as possible
-Transmission kick down cable as tight as possible so shifts are as firm as possible no lagging
-PCV enhancer to catch oil blow by from valve cover to intake.
-battery voltage stabilizer, supposively helps keep everything at a stable voltage
-Fuel Magnet supposively helps
-3.0? warm air intake next to header cone air filter best mpg is warm air
-Removed clutch fan for electric fan less moving parts and it is adj and kicks on at 205, and thermostat is 195 highest possible.
-6 new Bosch fuel efficient spray injectors, no more pencil spray old stock junk ones that prob leak too.
-Throttle body spacer with cyclone lines for better combustion and mpg
-Timing advanced as far as possible for better mpg
-Block heater so motor warms up faster to operating temp and into closed loop
-2000 jeep intake manifold that flows better and 15hp increase
-Tire pressures are all at 55PSI
-Run in neutral on hills and turn off if it?s a long enough hill, same thing at long lights it?s turned off.
-Serp belt is as loose as possible so spins as free as possible
-removed a/c and all that weight, and re-routed alternator in a/c's old spot so no more idler, fan or a/c pulley. smaller belt and less things to run around.
-Removed hitch, front driveshaft, spare tire and holder, rear seats, seatbelts, rear carpet, roof rack, and any other odds and ends that add extra weight.
-then rhino lined floors so its like a truck bed on the inside.
-All fluids in the jeep are the lightest weight possible diffs 75w80, tranny, engine oil 0w20, transfer case and all synthetic amsoil best.
-e3 plugs gapped as large as possible
-all high output wires, cap, rotor and coil from accell 8.5 super conductor for best possible spark
-high flow pacesetter header back exhaust 2.5 inch no kinks or sharp bends, high flow magnaflow cat too.
-run acetone, xylene, and 2cycle oil in gas at each fill up
-run z max every 5,000 miles in all fluids.
-all new sensors map, tps, iat, iac, map, 02 sensor so they are all working best as possible.


Did i miss anything or can i do anything else i drive 90% city and 10% highway.
