Frequently Asked Questions
Q: What does a stiffer actuator actually do?
A: It holds the wastegate closed harder and longer. That means faster spool, more midrange torque and a higher total boost ceiling – around 30 PSI tune dependent, versus 15–18 PSI on a standard actuator.
Q: Do I need a retune after fitting?
A: Yes, plan on it. The boost curve changes, and the tune should be adjusted to fuel and control it properly.
Q: Is the circlip included?
A: No – reuse your existing circlip or source one before install day.
Q: How do I know it fits my turbo?
A: Check the specs above against your current actuator (34mm bolt centres, 7.5–8mm mounting pin). Message us with photos if unsure.
