Snow stage 1 or 2
I was just wondering if someone could tell me if I should get the stage one or two kit from snow. I have a turbocharged stock 5.0 and it sees 13psi from time to time but usually around 8psi on the street. When this motor blows up I plan on building a 351 to handle 20psi so should I just get the stage 2 kit? I see one is progressive and one is fixed, im not very knowledgeable about water meth systems. I have a friend that has an AEM kit on his built SR20 but I'm gonna go with snow because of the warranty.
