I just purchased a Commander Limited 4.7 and I will be honest, my XJ and CJ days are making me a little less tech with this vehicle. That said, I watch Powerblock religiously and saw this little number on their show. Worth it?? I've seen a lot of pros and more horrendous customer service. Anyway, anyone else have or use one? MPG really get somewhat better?? Anything I should know??

Thanks, again, I am used to XJ CJ and 4.0. Figured if I could save a little on gas well it would be an investment.

Take care and thanks for your help!

Check out the mpg threads on here. It's a lost cause. It's not worth it to buy an aftermarket part in hopes it'll give you better mpg. You might gain 1-2 mpg but think of how much you have to spend. The mpg is the reason I had to trade in my jeep even though I loved it.

Thanks

Thanks for the heads up Brenden, had a feeling that was going to be the case... Plus, guess it wouldn't even work for mine anyways because only starts 2008 4.7 and up. I have 2007 4.7.

Thanks again for the advice though!!!
