First, welcome!
But, you're going to get a biased opinion here - guaranteed! If anyone has not been happy with their programmer (once they've received it) and the custom tunes (once they've received them) I have yet to hear of it.
Yes, there HAVE been a few hiccups. One member was unhappy because he ordered a programmer, was billed for it, and then it didn't arrive in what he thought was a timely manner. I know of two members who have had problems with the connecting cable from the programmer to the vehicle. There have been others who have had other hardware malfunctions. AND, some people have been waiting for custom tunes far longer than they thought they would.
In all cases, these problems have been resolved - mostly because Bill and Corey will put YOU first and will do everything in their power to make you happy.
So, how do they work?
Well, in the first place, your CAI may well be causing your truck to run too lean for it's overall health. The common wisdom is to get a custom tune if you're going to use a commercial CAI.
In the second place, they change the software in your vehicle's PCM (its brain) to improve almost every facet of your driving experience. Why didn't Ford do this to begin with? Who knows - but, ask anyone how they feel about their trucks before and after tuning with a programmer and I doubt you're going to find many nay-sayers. I've honestly never heard anyone call a programmer a headache!
They are easy to use, and the results are obvious from the start. I would not want to have this truck without the Gryphon programs.
There! Anyone else want to add to this?
Woops! I've just thought of something else! You get all of us for free, just by joining this community. One thing I learned in my years teaching engineering at the University of Arizona, is that a team of people committed to a common goal with complementary abilities will always outperform a lone wolf. In this forum, we are a team, because Bill and Corey have set it up that way. I'm always astonished at how much I've learned just by being able to talk to the other members. And, we all pass on what we have learned freely, without put downs.
OK, now anyone want to add to this?
