Truro claimed their first ever win in the Enterprise National League at the sixth time of asking after comprehensively beating Boston 3-0.
Truro, who became the first club from Cornwall to win promotion to the National League, lost their first five matches in the division but they went in front in added-on time at the end of the first half when Rekeil Pyke stabbed home from close range.
Tyler Harvey then won and converted a penalty four minutes after the break, having been adjudged to have been fouled in the area by Greg Sloggett.
The Tinners then rubber-stamped their victory in the 54th minute when a free-kick from Christian Oxlade-Chamberlain, younger brother of ex-England international Alex, was excellently converted by Will Dean.
