ok so i picked up a new TURBO XS blow off valve, and it doesnt say on any papers it came with how strong the spring in it is, also i just bought a new Performance Import Trends 38mm Wastegate, and also, no fricking listing as to what spring it came with, nor did it mention anything in the catalog when we ordered it. any way it all i can tell what it has, or is there just a general psi setting they come with and im too much of a noob to know this!
