If dish is still not quite right, loosen all the NDS spokes (1/4 or 1/8 turn) before you tighten the drive side, both by equal amounts if tension is OK, 1/8 turn more on the drive side if tension was still a bit low when you started. Retrue - remember, always tighten/loosen in pairs or you will change tension). Recheck dish, repeat once more if necessary.
