Yup, you guys are dealing with a private, in-house software developed genuine tuner - we don't send out slave files out there for other people to modify
(and potentially copy/ruin/distribute/etc.).
Intenseblue posted an awesome (thank you sir) diagram for anyone to follow the removal of an ECU, and as far as I know, there have been no known conflicts so far with the Sprint Booster (other than the problems the SB could be causing alone).
