If your track is small to medium size and tight/technical, 5.5T could be great, but for large tracks you may want to consider going up a bit in Kv on your motor or turning up motor (or even better, dynamic speedo) timing for the straight(s). I'm sure you don't need me to warn you to keep an eye on temps.

Generally you should never let a 2wd buggy pass you. Proper track etiquitte is to swerve wildly to discourage any attempted pass. If the buggy driver still insists on passing, let them get ahead and then plow into their rear on the next corner.
