Fall off a few degrees. I had a Genoa disintegrate after the Sunbrella unraveled in a Gale. Sailing too close (pinching) with an older, semi blown out sail will cause it to pump. As far as Jib halyard tension goes, I always have my Jib at max tension. Look at the wrinkles in the sail's corners to determine halyard and sheet tension. If the Tack area has any bow to it at the pulpit, increase the tension. If the wrinkles are at the Head, ease it a bit. I found that having the car forward and sheeting in tight allows a higher course but produces less power. Moving the car forward and sheeting in hard reduces twist as well. If the Sunbrella cover is loose and shot, it'll cost about $400 or so to have it replaced with Dacron stick-on IF, you removed the old fabric. If ya do, be extra careful to cut every stitch separately.
