Someone know how boom are very slow. I doing pressure adjustement , check flow meter on output boom pump, Vector are 100% for all fonction..... ????

If all functions are slow, it may be the hydraulic pump, but if it’s only some, then it will be the pressure regulator or electronic/software. Highly recommend hiring a serviceman, it’s a delicate and complex system that can be messed up badly if you just start turning things. Good luck.
