I have been very happy with my Edge, my truck is stock performance wise except for a drop in filter, so the canned tunes are working well. I might convert it to a gryphon down the road when I have some extra cash, but for now I am very happy with it.

The gauges are really nice to have as well...I like to monitor my tranny and oil temp to be safe.

 

I have to agree. I ran Level 3 on my 2006 screw (until it was totaled) and was very happy with the results. I had a CAI on it and never threw a code. I probably could have picked up some performance with a custom tune, but the canned stuff in the EVO worked fine for me. At the time, the Gryphon wasn't available yet.

The Edge Evo/Gryphon is such a simple, quick way to add a some performance and adjustability that it's hard to beat, and, in my opinion, are worth it JUST for the gauges. I'm constantly playing with mine! (and it looks cool....never underestimate "cool"!)
