Race ECM, and just mod it. I made 2 HP more without the PC than i did with

What does it being tuned on a dynojet have to do with it running too rich? I don't see the correlation...If it ran too rich, the the map was wrong/tuned wrong. The PC, just like every other EMS sees MAP and TPS, so I can't see why it would make a difference to switch to another system on something that has such a simplistic function.
