Ok I have done a search and I did not find what I was looking for.
I found this info that Im about to say in another site but I cant find it so here we go.
I have a tial wastgate with my rev hard kit (not installed yet). I heard that if the spring (inside the wastegate) is yellow then it is a 7psi spring but if it is red then it is like 12-15 psi. Is this true cause if it is i have a red spring in mine and i know my car is not ready for 12-15 psi
