Bah, some of you people need to man up. Speed Density is not that much extra fuss. After all, we're not senior citizens here (well maybe Steve..) weekly tuning is fun!
What DOES suck is when you have speed density and cannot tune it. I drive a 2gnt for my daily workhorse. 2gnt's came from the factory with speed density which only gets worse with age. Every time the weather changes I feel a slight difference in power delivery... kinda creepy.
