What's the best programmer for a 07 4.6L? I'm leaning I edge evolution but I'm not sure yet.

 

It's a lot of personal preference, I have the Edge Evolution because it can change a lot of parameters, and it stays on the dash where you can always monitor it. And it has the nice mount that flows with the interior of the truck. Hypertech and superchips don't stay plugged in and don't mount nicely, in my opinion.

 

Read this thread first and then we'll be happy to answer any other questions you have.
