Last time out in front of their home fans at Adams Park, Wasps were convincingly beaten 28-5 by Bath.
This led to Young asking for more from his players and it arrived at the Madejski Stadium as a penalty try - awarded for James O'Connor deliberately knocking on - and the boot of Andy Goode led them to a seven-point Aviva Premiership success over their capital rivals.
It was Wasps' first win in Reading since March 2008 and Young insisted it was no more than his side deserved after they answered his war cry.
"It was nowhere near a perfect performance - we still made some mistakes, which put us under pressure - but I thought the players showed real courage and commitment to each other," he said.
"They showed how much they wanted to get the victory with their display during those last three minutes on our line. If you give someone that amount of possession half a yard from your line it's probably easier to score than not.
"We were honest after last week. I expected a reaction. I wanted to see how much they wanted to wear the jersey and I thought they reacted really well. They showed the commitment and attitude I expect.
"There's still a lot of rugby to be played. It was an important game because everything is so tight.
"You win one game and you're sitting a little more comfortably and then you lose one game and you're looking over your shoulder. It was very important for us to keep ourselves in the mix."
O'Connor and Shane Geraghty kicked all of London Irish's points as they failed to mark Topsy Ojo's 200th appearance for the club with a victory.
The Exiles pushed hard for a try at the death and, although Wasps' Charlie Hayter was sent to the sin-bin, they could not cross the whitewash - much to Brian Smith's disappointment.
"It was very frustrating," the London Irish director of rugby said. "They had a simple game plan and, to be fair to them, the mugged us on our own turf.
"They kicked long, they scrummed for penalties on their ball and they flooded the tackle area and you could just see the frustration as we couldn't get going.
"Uncharacteristically, we turned the ball over as well and made some handling errors, which we were flawless in last week.
"I felt it was probably our poorest performance of the season and to have that happen at home is disappointing."
