I have done some searching on this subject, but after all the reading I haven't come up with a good answer I'm not looking for power so much as I am the most amount MPG's I can get from the addition of the box.

I'm sure the Smarty on it's mileage setting will net the best increase. One problem, I tow almost daily with my truck the Smarty's mileage setting probably will not work too well for me.

It seems the timing from the EZ is supposed to net a small MPG increase. Would a VA box yield a better MPG increase? Would a Comp on a lower setting yield better MPG's than an EZ? Would another setting on the Smarty be the way to go?

I also plan on installing a set of 275's so I am hoping to pick up a little mileage there as well.

Thanks for your suggestions.

BTW - I would like to purchase something used to keep my cost down so if you have a used box that you are looking to sell please contact me.

 

Quad tow module (I don't know the exact name) Might be one in the calssified.
I think it gives you 65hp???

 

....when you choose one (I chose the Edge EZ), ck the price @ autoanything.com

 

my truck along with many others netted best milage gains witth smarty on 9 not fuelsaver,with the smarty and bd 130xxx sticks im getting the best milage my truck has seen,i used to have a oldvanakken box that only plugged into the pump and it was good for milage too,i found the comp didnt do much for milage,didnt make it any worse though and nice power gains but my truck runs the best and perfroms great with the smarty on 9 and bd sticks,comp is gone from the mix.
