Where in the sky do you calibrate and what exposure setting are you using? I use 2000ms max Dec and 2000ms max RA durations on a 345mm guide scope with ASI290mm at 1 second exposures on a iEQ45 mount and usually get less than 0.6 arc-sec RMS guiding. Calibrate above 45 degrees elevation in the sky and be sure you get a multi star lock. Hope this helps.
