Feeney, who is 191 points from the series lead, admitted Triple Eight needs to raise the bar to keep with Erebus.
“It was a pretty good Sunday for us, and even better that we get to bring some silverware home,” Feeney said.
"We got a win and a second today, and #97 had a great recovery in the last race.
"I still feel like every weekend I’m only getting better.
"It was a bit over 12 months ago that I got my first podium here, so it was great to be back in Tassie.
"I feel like we’re continuously building and building, and I’ve been driving a lot of cars as well.
"We have to keep lifting our game because the Erebus boys have certainly raised the bar this year and we have to keep hunting them down.”
Kostecki leads Brown by 87 points, with Mostert 166 points down in third. Van Gisbergen is fourth, 172 points down.
