the horsepower out put was substandard. and I actually got better fuel mileage in the extreme mode then I did in the eco mode.

Installed the Edge Evo a week ago. The install was only tricky when mounting the dash pod- it was tough to get it to lay flush and I'll have to spray paint it since it came in grey (my dash is black). As for the unit itself I was impressed at the overall improvement in performance right out of the gate. I set it to Level 4 and haven't looked back since. It even woke up my Gibson Extreme cat-back exhaust system giving it more of a growl even under normal driving conditions. Looking to get an improved air intake system to complete the performance upgrade.
