Yep that is a good kit. Start out running as it is setup by default.
What I would do is Get the truck up to full operating temp, find some flat ground and get up to steady cruising @ 55-65 mph. Take note of your egt
at this speed. That is a good place for where to set the starting Min egt
on the first stage likely 500-700f . Set the first stage max to 1000 f and the also make that the second stage min start point. Set max egt
to 1400 for 2nd stage . You can then play with duty cycle to get things tuned in. After driving it a bit you can try adding in curving based on boost as well as EGT
for the second stage. This will help fine tune things even further if its even needed. You can give equal or more weight to egt
or boost to find what works the best. You can also try lowering the max EGT
to see the effect. Many things to try as they offer a good number of configuration options.
Cooling Mist's pump is great in that it will hold there pressure even with a couple of the largest nozzles.
Something I am planning on doing to improve things a bit is to go with using two smaller nozzles for each stage instead of just one larger one. This will improve on the atomization especially during the curve up to full flow. I am doing this on my next system on my current X. Also look at the improved injectors they offer that further increase the atomization. Atomization / flow psi
is key to getting the best perf from water injection from what I have seen. For a tank the 7 gallon size is nice as you will be running all the time but he price is a bit steep. A great option is look for a fuel tank from a riding lawn mower or something similar. It already will have the port for the water outlet and mounting straps or holes. At these sizes with normal driving you should only have to fill up when you need fuel. Mix some water soluble oil in with distilled water will help keep things lubed and prevent winter time freezing.
The other thing you could do for extra safety other than the settings is to add a solenoid that works off the ignition or other switch. This will prevent water form ever being able to run and fill up a cylinder and hydro lock your engine on you.
