i recently purchased a 2000 jeep grand cherokee 4.0L V6. It gets about 16mpg and i am looking to buy this hypertech max energy to get me better gas mileage. i just want to know if anyone has put it in their jeep with the same size engine as mine and if they have had any problems with it. And if you have the same car with the same engine and you have a different programmer that is great let me know. thanks.
Has anyone put a programmer in their 2000 jeep grand cherokee 4.0L V6?
