apparantly they have changed their kits, since i have purchased mine. mine will inject based on boost, or egt, or boost/egt.
it seems they have done away with the egt, and went with a autolearn feature.
the progressive controller, imo, is well worth the money. imo so isnt the second stage, but when i buy something, i buy more than i need, so if i need it in the future regardless if i need it now, its there, and i dont have to buy another something again.
like lowdown has, its a on/off switch. a fixed rate of water. so if he could use a little more, or a little less, at that particular moment, it dont matter, he's still getting the same amount.
mine will vary from about 150cc's per min, to about 650cc's per min, give or take a few, and this is customizeable, based on the nozzles i put in it, from a min of 50 up to i think i have a max of about 1000 or 1100 if i want that much.
every situation, i have the right amount of water i want the motor to have, based on how i have the controller set up.
if your just getting hot in the upper rpm's, or when you tow heavy rarely, then a single stage kit will work fine. set to come on right as the heat gets there, and keep it cool, and not the rest of the time.
i wanted alot more control of what i have.
