Not taking anything away from hypertech because that is your choice of tuner, but your comment about waiting Til your truck is out of warranty before custom tuning is comical at best, you are programming your truck with hypertech and gonna void your warranty just the same as a custom tune. Either one of them can void your warranty if found in your truck. That's a fact.
Also the reason sct is a better programmer is because you can datalog your tunes to make sure they are running safe, you never know when the fuel turns bad or the tanker guy screws up and puts 91 in the 93 bulk tank. Stuff happens. All trucks are different and react different to tunes, programmers like hypertech, superchips, edge, and even sct canned are generic and fit all model years from 2011-2014 ecoboost trucks. There is a lot of guys that have problems with their custom tunes and some that haven't and they are all made from the basic mold but with different strategies. Once you datalog you will find these imperfections and its fixed. And I'm willing to bet if you datalogged your hypertech you would find that it's not as safe as you think it is.
Well CB I do respect your input because I know you've tried 'em all. I don't appreciate the comical comment...but as I stated in my first post on this thread....it always opens a can of worms when someone asks this question....and not just here on this forum. I understand the logic in your opinion...and I will be data logging eventually. That said, it is only your opinion. I know how Hypertech tunes, and while some of your comments about "generic" tunes are correct, they are only assumptions, as I know for a fact Hypertech tests each year model and tweaks all year models and updates constantly. I have some customers and friends that are custom tuners, and what you've noted about the GOOD ones is correct. However, I don't personally know an EcoBoost custom tuning expert. I have run various custom tunes on Mustangs in years past, but they were all non-turbo, normally aspirated engines.
The reason I refer to them as "safe" is that I know they do build "fudge factors" into their tuning, like the fuel issue you mentioned. Hypertech only states "87 and Premium" fuel options. Premium = 91 octane in their tune...that way a guy like me that can't always get gas at the same station is "safe"...ok...granted...safe-ER....they have also tested (data logged and track tested) some of the "custom" tunes that you guys are running. Some of them are running dangerously close to the limit of the stock fuel system on these trucks, and I don't mean just pressure.
Now...in the interest of not escalating a programmer war....I'm done here....it won't help the OP for any of us to sit here and try to one-up each other's vast, well-read, and real-world tuning experience. If any of us were experts...we'd be making a living at it now wouldn't we? It sounds like he only needs an 87 tune for fuel economy anyway.
Take a chill pill on the inflammatory comments man. We are all just trying to help each other learn.
PS. The reason for my waiting until after my warranty is up, is not related to being "caught" with a programmer by the dealer...for that I would whip out my Magnuson-Moss Act

....it is more related to taking the chance of running a "full-tilt" tune, and breaking something because the tune was pushing the limits of whatever...say for instance running the fuel rail out of fuel for a split second and scorching a piston (seen it). After my warranty is up, I may be willing to take that chance.
