With the current crazy gas prices rising daily, lets share ways to maximize our MPG.
0. I modified my front lower valance by cutting on the factory line/seam making it identical to an FX4 valance (didn't notice any added MPGs)
1. I installed new NGK colder (7) than stock spark plugs (stock plugs had 47K)
2. Unloaded my 5Star 93 Performance tune & loaded my 5Star 93 Daily street/tow tune.
*I am now netting an AVG 17.2 MPG. Up from a 14.4 MPG AVG.
+3. Next I am mounting my stock (275/65/18"x8.5" Michelins) tire/wheel package (current tires/wheels= LT285/65/18"x9" E rated/10 ply General Grabbers ATX on Mayhem rims ) & will update this thread with the added MPGs.
+4. I may load my 89 Daily/tow 5Star tune.
+5. Never fill up the gas tank more then half full (I have a MAX | 27 gallon tank).
+6. Remove the spare tire.
Background, I also 90% of the time drive this rig unloaded/empty with only me in it. Run in 4A 100% with 3.31 rear gears.
Looking forward to the community's feedback & conversations!
