My profuse apologies if I am recreating an existing post.
I tune quite a few PD motors in VW Polo TDi, Audi A4 iterations. Generally these are the PD100/PD130 motors. They go extremely well, but we keep running into heatsoak issues. The turbo is standard VNT15, and layout is single side mount intercoolers.

Has anyone worked with Aquamist on these? Could use some advise on the following;
1.) optimal jet locations.
2.) Which system is best suited to the application (would a 2D do the trick).
3.) With respect to 2 above, what jet sizes are best and at which boost level should it be triggered.

Sans methanol addition (most of these are daily runarounds), how much benefit will WI be for pure water, and are there any dangers associated with WI that might not be present in petrol applications, bearing in mind that CR is higher to begin with, without WI?
Advise will be most appreciated!
Cheers
