Frolunda trailed after 20 minutes following Joona Koppanen's goal for Lulea, before a relentless second period from the away side as they scored six goals in 11 minutes, with Graeme Clarke scoring twice and Bosse Meijer picking up three points.
Filip Eriksson and Valtteri Puustinen scored either side of the 40-minute mark to add some gloss for the hosts, before Max Westergard made it 7-3 late on to join Clarke and Meijer on three points each. Frolunda are top with eight points, while Lulea sit 11th with one win and one defeat.
Newly-promoted Bjorkloven twice surrendered the lead but finally got over the line in overtime to move onto two wins from two, winning 4-3 at Orebro, who sit fifth despite two defeats and one win so far.
Robin Kovacs and Marcus Nilsson had the visitors 2-0 up in the first period, only for Patrik Karlkvist and Jesse Ylonen to draw Orebro level in the second. Albin Lundin's early strike in the third was soon cancelled out by Milton Oscarsson, but a second for Kovacs after three minutes of OT sealed it for Bjorkloven.
Charles Hudon's overtime goal - his second of the game - gave Djurgarden their first two points of the season with a 4-3 success at home to Vaxjo. Farjestad remain second in the standings with seven points after they won 2-1 at home to Rogle, as another overtime winner, this time from Nikola Pasic, gave HV 71 the win, 4-3, to dampen reigning champions Skelleftea's start to the season.
