Yes Di is direct and you know CR, from what I've been reading fitting the NADS is very worth while for both, having just fitted one myself. My EGTs are now 200 deg C ALL THE TIME, where as before 450- 550 deg C. plus now I control how much boost the engine gets. high on the must do list. need a pyro and boost guage before you start, on the plus side a little better on fuel, I've picked up an extra 30 K per half tank, but will be checking again next fill . Hope this helps a little
