Wasn't privy to the actual hardware or software development and that doesn't matter as I wouldn't know what I was looking at anyway, but did spend every single dyno testing session with them. The short of the story is after abusing my car for a month on the dyno, driving the streets of Dallas under different load conditions and numerous tweaks.......The car did not make a single hp more than the stock ECU when tuned with OBDII LT1.edit software.
