I think they just messed with the mapping not completely sure because I didn't want to get in their way and just watched from afar. There is some great tuning software out there for the Evo though, forgot the program I used since last I used it was 2 years ago but we'd hook the laptop up and mess with the maps while going down some back roads. All I know after adding a new fuel rail, the cams, bigger fuel pump, etc the HPF's tune really helped out with making the car perform without fail.. at least until my exhaust manifold warped.
