He used to sell Enthalpy and JWT ecu's on craigslist too,
[email protected] was his email. What this tells me (and most people who know about rom tuning know) is that he would buy other companies ecu's, copy them, open them up with rom editor, make a few changes, then resell his "new" program. This can all be done with about $100 in hardware/software. The chips and daughterboard cost him about $50, so anything over that is pure profit. Im 100% positive that he has not tuned almost all of his programs on a dyno and that he used theoretical values for programming, which by the way are already done for you on the Free Programs that are out there.
