While we can't get into specifics as for what we have access to that no one else does, I will say it's not like it's only one or two things. We brought all of the development for software in house. Too many times over the years have we been burned by aftermarket companies that make software, that map stuff out incorrectly. Also, what if it's low priority for them? There are platforms we have been tuning for multiple years that no other company even bothers with. If we could do the same thing using something that's already out there, we would, why add the complexity and extra work? The short answer is because we care more about the results we offer than anything else.
