Unhappy at last Saturday's 30-20 victory in the first Test in Wilmington, Bowring was heartened by his midweek side's 55-23 win over a USA Development XV in San Francisco.
However, Bowring, whose side has now scored 179 points and 27 tries in three wins in America, is look to improve further. "We will be looking for a step up in the attitude of the players and the quality of our performance in the second Test," he said.
Wales played into a strong wind in the first half at Saturday's Test venue, Boxer Stadium, and the tourists' ran in five tries as they established a 31-13 lead at the interval.
Andy Moore, the acting captain, opened the scoring with a try in the second minute and he was one of four players in the back division who scored twice.
The Swansea full-back, Matthew Back, and Pontypridd centre Jason Lewis marked their tour debuts with a brace of tries each and the Bridgend wing, Dafydd James, touched down twice in the second half.
Lee Jarvis, the Cardiff outside-half, kicked five conversions to take his tour points tally to 44.
