For those of you who may not be familiar VF Engineering and 
our HEX Tuning software brand; All of our s/w development, 
testing, validation, and measuring is done entirely in-house
at our Anaheim, California

The bulk of our initial testing is a mix of controlled dyno testing 
in-house, as well as road and track testing for drivability and 
endurance. Our goal is never based on targeting peak power, 
but rather to find what we determine to be the equilibrium 
between area under the curve and reliability on traditional 
pump fuel.
