my setup was total opposite,,im runnin a cheap water inj. setup,, i used an ol washer bottle w/ pump,,and i let it rip into the intake before the turbo,, i used an old carb. jet in the end of the line,,now remember its crude,,but that turbo sure atomizes the water!!,mines actuated bya button on the shifter,and i canhonestly say it works,,cause cruisin thru pa on rt 80,,goin up a hill,holding steady speed like 75mph,and around 8 pounds of boost,,if i hit the water,,i have to back out of throttle,it starts toaccelerate,,to get it to hold steady speed at this point,ill usually drop2-3 psi of boost,,,oh i use plain ol blue washer fluid,,,had this setup on for 2 years,,when i removed turboto swap onto my tdi,it looked fine,,nowater erosion or anything,,,,,,,just my 2 cents,,and thats all my power adder cost to build too,,egt is cooler,, imayhook up a setup w/ a psi sender to come on auto,,,but it works!!
