I asked the same question about a month ago and rec'd no answer, or guesses. There is definitely a hesitation when you stomp on the gas from a standing start. The 6-spd tranny does get good mileage. Maybe it is setup not to throw away so much gas in 1st & 2nd gear. Maybe a Dinan upgrade will cure it? I definitely makes my heart also stutter when jumping out into traffic.
