I have a edge...... It's nice to have the readout but has limited tuning abilities..........
This is the ONLY product I recommend...... Which is essentially a edge put it's "a wolf in sheeps clothing"
A Gryphon tuner for Power Hungry Performace- the guy pretty much built the edge evo for Edge... He knows what he is doing and he car make you CUSTOM tunes for the EXACT upgrades you have put on your vehicle...... Add more parts- get another Tune(for a fee of course)..... Bottom line is you can keep adding parts- pulleys, charger- whatever and he can make sure your truck will run the best it can for the parts that are on it.
