[Serenity Now]

Hi, this is my first thread and question to the FJ community here, and as I have my FJ in the shop to get revamped after buying used, one thing I want to do is buy a performance chip to improve my HP and get the most out of my already dwindling gas mileage because of larger tires and a slight lift.

You might be able to get a few more horsepower, or you might be able to get a little more mpg, but you're not going to get both from a chip, or Toyota would have done it already.
