Truro claimed their first ever win in the National League at the sixth time of asking after comprehensively beating Boston.
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.
