Turbosmart optional 30 psi springs are offered for compatible Turbosmart blow‑off valve models (TS‑0501‑12xx, TS‑0505‑12xx, TS‑0506‑12xx). These springs provide a firmer internal spring rate to raise the valve opening pressure to approximately 30 psi, allowing tuners to match valve response to higher‑boost setups without replacing the entire valve assembly.
