County won the second-round tie 3-1 on penalties at Molineux as Wolves trio Bjorn Sigurdarson, Kevin Foley and James Henry all missed from the spot, coming with the clash having finished goalless after 90 minutes.
County dominated virtually the whole game and the result was no more than they deserved.
And a delighted Kiwomya is now keen to see them build on it - coming hard on the heels of last weekend's 4-0 success against Crewe.
He said: "The last three games we have played really well. As long as you are playing well and creating chances that is always a good sign.
"I am very confident but I always have been. I didn't get too low when we weren't getting results as I always thought we could climb the table.
"We do want to do well in the league. I don't like being towards the bottom. I think we should be in mid-table pushing up.
"That is what my ambition is and if we are around there after Christmas then we can push on.
"The start has been disappointing. But I don't look back too much, I look forward."
Kiwomya continued: "I thought we played really well against Wolves and we were brave.
"We had two great chances in the first half and we knew Wolves would come out in the second half and be better and put us under pressure. But we held the pressure and we should have scored at the start of the second half which was disappointing.
"But I can't fault them, they are a fantastic bunch of lads and their confidence is really high."
