I am looking to find out from the experts here about how well the Hypertech programming will work on my 08 4.0 and of course if it's worth it. I am mainly looking for better fuel economy but, of course at the same time, extra power is always a plus.
Thank you for any help and/or advice.
I have read through the previous posts about this but, I haven't found anything that would be recent after 2011.
