I lifted the FJ 2 inches, put on bigger tires and an ARB bumper. I then added a Airaid, JBA headers and a Cat Back system. nothing really improved the mileage or performance until I put the Unichip system in. Thats when it all came together. I haven't checked the mileage yet but it sure made it much quicker....
You have to specify the the aftermarket things you have done and they will customize the chip for your setup. You can also go to a authorized tuner center for a custom job on a dyno. My FJ finally hauls butt and has much more pick up. I hope it improves the mileage as mine had slipped to about 14 hwy.
I paid about $620.00 for mine, but it varies on the web. They also plan to add a setting for E-85 fuel which is over 100 octane and 40 cents a gallon cheaper than gas. I already run a 50/50 mix of gas and E-85 and she loves it. I used to have a sooty/black powdery inside of the tailpipe but now its a nice brown color and clean.
