Depending on gearing, uhm...well anything is possible. To an extent.

Wait wait wait? It's an automatic? Oh lord. Did it shift into third before, or after you went past a quarter mile? My problem was that my car shifted right before. "shifting" it yourself doesn't help (this is how I ran my 18, heh). The fastest way I found was to put it into first, and once i got going just put it into drive and let it shift itself. Either way, I was still slow. And well, hmmm. 15s for a civic? My friend was driving a 2004 Cavalier 2.2 ecotec and he aws running mid 16's (not the same one with the standard). Anyway, I have a hard time believing you ran a 15, or the track you are at has issues.
