Also i think the DEP is designed more to get higher top end than the big-one, which with its smaller/shorter expansion chamber is possibly designed more with acceleration in mind. For more detail on the subject of 2-stroke tuning have a read of the book "2-Stroke tuning by A.Graham Bell". Also, if you find the time, introduce yourself in the bar section of the forum .
