I did a search of the forums and got some good info on the Edge EZ, but had a couple more questions. Is it NECESSARY to do any additions modification (like high-flow air filter and/or muffler) to use in conjunction with the Edge EZ? I would think that the extra horses would raise the EGTs. Next, the Edge web site at http://www.edgeproducts.com/dodge_ISBE.html says that you can "set the unit to zero for heavy towing without having to unplug the module". My truck has plenty of power unloaded. The only reason I would install this product is to help while my Lance camper is loaded and I am trailering my Jeep. If it's supposed to be turned off under these conditions, then of what use is it? I'm not interested in "smoking" the Fords and Chevys on Main St.
