The graph i posted does make it appear that way, but the highest rpm i took it to while tuning was 7600. The rev limit is set at 7400 i believe. Its in the cal file above. We have a optical rpm pickup on our new dyno at the shop. At the time of the graph i was using a rpm pickup method called "snapshot". It reads the rpm off the dyno roller. Sometimes it doesn't work so great. When using the optical rpm pickup on the crank or any other pulley on the engine it works wonderful. At the time of the graph i wasn't using it as i should. I wasn't tuning at the time either though. Although the rpm's are off in the graph the hp & torque readings are on point compared to when the rpm readings are right.
