Megs, some diesels are lazy, and some are not. Aside from the driver, it can come down to just the basic tuning of the vehicle, and improving air flow, etc. Eg, our over-half-a-million-k's patrol is non-turbo (diesel), and trounces turbos, petrols, and even race built 4B's. Why? Cos of how its tuned and other bits and pieces (ie, better flowing air intake and exhaust). It's what we do for work, so if you want some help anywhere down the track, let me know.
