Edge doesn't ship the Pulse anymore, but there may be a few still around at various vendors. I've got one I bought a couple of months ago for a very good price. It installs under-the-hood like the Edge EZ. However, it has the pump wire option, and four power settings along with four sub-level settings for defueling and smoke control. In order to program it, you've got to set jumper switches, which you can access by removing two allen screws and a metal plate. <br><br>Mine works very well, but honestly, unless you're worried about taking it off quickly (for trips to the dealership, perhaps), or unless you can find it at a good price, another Comp will probably do you better. The Pulse is really a Comp without the in-cab adjustment feature. If you do get a Pulse, make sure you also get the special MAP plug for the '02 model year. <br><br>GP
