Also, on another note, We do things differently. Many tuners require the customer to be the guinea pig and send logs and files back and forth. We, on the other hand, purchase these cars so we can do development in house at any given time, and send out those tunes. The reason we don't support data logging is the is no method today that provides you with the proper information needed to tune these cars the correct way. Occasionally you might luck out and make some changes that work based on the incorrect data being logged, but it's just that. Luck. This is why we own basically every record for EcoBoost vehicles. We bothered to make the investment to have our cars be the development mules, not our customer's cars to ensure that what we are developing is done properly. This is the only way to properly develop tunes as it ensures you are recreating the exact situation that needs addressing.
It also makes it so a customer does not need to risk his car, license, or life getting data logs. We worry about that with our car. This also gives the peace of mind that, in the rare case there is something wrong, that it's our car taking the beating figuring it out, and not your own.
