Wondering if anyone can assist, I have an RB50, running 21.5, which has no power. It has the latest firmware, (1.4 I think it is) and at full throttle the rpm is very low. No timing or turbo boost can be heard either. Have tried a new sensor cable with no effect. Other thought was maybe I have incorrect settings on it? There was no attachment with firmware for revised hand held programmer settings, but maybe I have them set incorrectly. Perhaps someone can link me to the current sheet for the hand held unit so I can check against mine?

Thanks in advance.
