Superchips was the first tuner I had for the ecoboost. Partially because it was out early on. It was ok. Stepping up to a SCT you see bigger gains but it doesn't feature some of the items of the superchips like monitoring sensors etc unless you data log, then it surpasses the superchips.
Then you step up past the canned tune with a custom one. The difference is astounding! From getting rubber in first to getting rubber in first, second and third!!!!
The main reason why you want to go with a custom tune is that it is married to your vehicle. You data log it, and can see how your vehicle is reacting to the tune and also to see if any changes need to be made. You can't do that with super chips, the sct canned tunes are probably no better than the super chips. It is just better to run custom tunes that are married to your strategy code. There are 5 major brands out. SSI, MPT, 5star, Unleashed, and Livernois. Livernois uses the mycal device. I recommend sticking with the sct device. Can't go wrong with any of those. All good
Me personally I think SSI, but that's just my opinion, MPT has a great race tune, unleashed has a decent one too. Livernois is proven also. I think 5star tunes are really how the truck should come from the factory. Strong and smooth. They are all good. Good luck with ever you choose, all of them are safer than your stock tune and all of them will think you've just bought a new truck.
I owned a Superchips for my Titan. It's not a bad tuner and you do have some features such as speed limiter removal, timing changing and a few other options. But you get what they want you to have not a tune for how you setup your bolt on items, or custom tune options. It was my first tuner and for a newby I did not want to worry. When I came over to the Ford I wanted something better, more options. I went with the SCT and purchased it through 3 stage and 5* for my tunes. five star provides custom tunes and I think lifetime updates which you don't find often. I chose 87 performance, 93 performance and another, but I am running the 87 and really impressed how it works nice smooth. in the summer I plan on testing out the 93 tune..more to follow in the summer.
sorry for the long post but you asked.
