I'm ordering a programmer this week! What is the best programmer for the money? I see gryphon and edge cts is the top 2 most talk about. What exactly is the difference and my truck is completely stock. All it has is straight pipes with high flows cats, no mufflers. I want a programmer that won't mess up my truck or tranny or motor. So what's everyone's opinion and my truck is a 2007 5.4l f150. Thanks
