The vehicle is the Mitsubishi L200, named the "Triton" in some locations on our insignificant little planet.
The engine is a 2.5 l, VG turbo, 400 Nm at 2000 - 2800 rpm. Vehicle weight is about 2000 kg. (now you get a chance to practice some metric units...)
I found some power curves on a site belonging to an aftermarket chip trimmer. The green curves are for the stock engine. The second graph is a bit unusual but it illustrates the turbo lag as the time it takes from throttle until torque. If one is to believe the graph, the lag is 2.27 seconds until 90% torque although it doesn't say from where in the rpm-range. This approximately correlates to the driving experience at a speed matching 2000 rpm. (smooth clutch engagement and then almost full throttle)
