First of all sorry for the forum, Since we did the update last week, It is giving us hell. Chance still has to fix the rest of the code.
With the DO1-DO2-DO3 nozzle it really does not matter, They all spray at above or just at 200psi the droplet size is around 18 microns so it atomized perfectly to not harm anything. We cannot say the same for other vendors nozzles because ours are custom made. But the droplet size is key to safe pre-turbo injection. I would slap in the DO2 and take here for a spin. You will not be disappointed in the power increase even with strait water.
Which country are you located in?
Here's a troopers install to give you a go by. Set it to come on around 6 to 7 psi if you want to see what it does with max power use a 50/50 mix.
