Im looking into getting a snow performance kit with the safe injection for my turbo set up. How does the wastegate solenoid they sell work. Does cut off boost when something goes wrong (like lost of meth flow or clogged lines). It doesnt indicate what it does so dont want to buy it without...

i saw that the prestone deicer is a little different now. it has silicone in it. is it still useable for the boost cooler? if not where can i find meth?
