The higher the "power increase" the higher your EGT's will go.

They allow you to keep your foot in it without burning anything up. Also, shifting strategy is different with a tow tune.

For example. I have the 40 high tow. If I drive completely unloaded with this tune it shifts so hard I feel like I'm getting whiplash. You wouldn't want to do that with a higher hp tune.
