I just had my 07' Rubi JK lifted/larger tires. (Daystar 3" lift and Nitto 35" Mud Grapplers) I got the look I wanted but am little surprised at how much MPG I lost. I am only getting around 11MPG around town. I only have a few miles to work/gym/sitters so its not too big of a deal but I am looking for advice from anyone who is running a similar set up.
I have been looking into an intake (RedRock 4x4 Cold Air Intake Kit $139.99 and a programmer (Flash Cal Super Chip Programmer $149.99).
I am a little strapped at the moment on extra cash after finally getting the JK set up, so I am looking for advice on a affordable way to improve engine performance/gas mileage? any advice would be much appreciated..
Also looking to increase horsepower/torque for pulling my 20' bass boat, anyone with advice or experience with the parts mentioned above please give me a shout. thx Andrew
Take $1500 and buy a 1998 Nissan Sentra with 200,000 miles for the days you want good fuel economy.
With the constraints of tire size, vehicle weight, and wind resistance that you have, there is nothing you can really do (along the lines of a CAI or chip) to improve mileage. A chip can't diminish wind resistance, or lighten your tires or rig.
I made more modest changes to my rig, it's less capable, but I like exploring and getting 20mpg. I have to drive less than 65 mph to get 20 mpg.
Try dropping your speed to less than 60 mph. Also adjust mileage for your larger tires. Your odometer may be off by 10 or 15 percent. Of course you'll still be less than 13 mpg.
It takes a lot of juice to move a lot of weight, and it takes even more to move it fast. There is no beating simple physics.
