Is the EZ Edge a good investment for the 600. Just bought the truck and want to know if this helps. And how much would one cost. Who else makes simular product?

 

Welcome aboard, fairman. Here's a thread that you should see:

Investment? Certainly not in the traditional sense, but neither is a truck. It will provide you with hours of quality entertainment, and some claim a modest improvement in fuel economy, especially if you have the discipline not to drive the truck in such a way that you realize the entertainment that the box provides. If you realize a mileage improvement and put about a zillion miles on the truck it might barely pay for itself.

Other manufacturers include TST, VanAcken, Banks..........there are several.

 

I love mine and would recomend it to others.

I would also recomend some gauges, exhaust, and intake, to take full advantage of the box as well as gain a couple of MPG.

My 600 went from about 10.00MPG at around 12.7MPG, (god I hope they hurry up with that TSB!!) after the goodies.

 

I guess this question doesn't pertain to high performance, if its an investment question.
