Installation Write-Up & Review

Having come from a background of CJ’s, TJ’s and XJ’s that all came with nice torquey 258 or 4.0L I-6 engines, it was hard for me to get used to the lathargic 3.8L V6 that the JK’s come with. Granted, my previous Jeeps may not have been speed demons but, at least wanted to get up and go as soon as you hit the gas. More than the motor, the problem with lag that the JK’s have comes from the fact that they now come with an ETC or electric Throttle Control. And, while there are solutions available that can help address this lag by allowing you to reprogram your computer, there is another solution that does a great job of helping out as well – Sprint Booser.

After installing new and larger tires on your Jeep JK Wrangler, one of the first things you will notice is a loss in power. And, depending on how big your tires are over stock, that loss in power can be significant. Of course, the best way to address this power loss is through the installation of new differential gears with a higher ratio. However, even with new gears, most people that I know of find the JK’s 3.8L V6 to be on the gutless side and would love to have a bit more power. Fortunately, there is a great solution to this problem and it’s made by Superchips.
