Since it removes the long term fuel trim and allows the ECU to learn faster, it only enrichens if you need it. It also advances timing. The powerchip is similar and improves power approx 4hp across the board on the dyno... I expect this would do the same as proECM and the Manufacturer claims max 12 ftlb gain and about 4hp from the dyno plots I have seen previously.
