There are a myriad of tuners that have come into the foray now.....
But the two companies that have been in the Ecoboost platform since the beginning, are Livernois and Unleashed Tuning.
Both are competent, and both offer great service.
The MyCal device sold exclusively through Livernois, does allow them access to more parameters over the SCT device.
Both companies do sell/support the SCT however.
LMS also does have a close partnership with FMC. Particularly their Racing Division. Like this/close.
So, it goes w/o saying that that relationship does foster an edge so to speak over all of their competitors.
But again, there are plenty of tuners to choose from at this point.
I'm sure the rest of our membership will chime in as to their opinions/experiences.
Either way, obtaining a tune (from whoever) is bar none,
THE BEST BANG for your buck as most of the Ecoboost platforms appear to have been severely detuned from the factory.
Enjoy your newly found speed whenever and whomever, you decide to go with!
