It is very hard to change the "true" throttle response of a fairly large diesel (a lot of rotational inertia; partly as it has to smooth out only having 4cyls), plus the turbo takes a little time to pressurize (no matter how much you up the boost, it's still a "laggy" device).
A remap will give more torque, and will give therefore give an impression of better throttle response, but it is more that it just gives you more "push".
Many older guys will recall that it took years to get throttle response on petrol cars, which had started to use fuel-injection as standard, up to the levels of say, a set of Weber carburetors... FI does have other benefits though! Similarly, when turbos started to become a standard fit, throttle response was dire, and only recently some of the better cars are starting to feel like they are getting there...
What you might try, given the truck has an electronic throttle, is one of those devices that re-profiles the signal that is sent to the ECU from the actual pedal. Sure, all it does is fool the ECU into thinking you are faster to press the throttle further down, but it sounds to me like that could work.
