25 PSI Wastegate Actuator – F44 & F55 Turbos
Heavy-Duty Spring | Lifts Total Boost to ~30 PSI
Running an F44 or F55 with the standard 15–18 PSI actuator? This 25 PSI heavy-duty actuator is the missing link – hold higher boost without the gate creeping open, lifting total boost capability to around 30 PSI on a suitable tune.
📦 What's Included
- ✅ 1 × 25 PSI Heavy-Duty Wastegate Actuator – suits F44 and F55 frame turbos
🚀 Why Upgrade the Actuator?
- 🔒 Stops wastegate creep – the standard spring bleeds boost early under load
- 💪 Holds boost to redline – stronger spring keeps the gate shut until you want it open
- ⚡ ~30 PSI total capability – with a boost tee or tune-side control on top of the 25 PSI base
🔧 Compatibility
⚠️ Tune required. Raising boost without appropriate fuelling and tuning risks EGT and drivetrain damage. Pair with a CRC Boost Tee for fine adjustment.

❓ Frequently Asked Questions
Q: Do I need this if my turbo came with an actuator?
A: The F44 and F46 ship with a standard actuator. If your tune targets over ~20 PSI and you're seeing boost taper at high RPM, the 25 PSI spring is the fix.
Q: Can I adjust it?
A: Preload is adjustable at the rod end, and pairing with a boost tee gives fine control above the 25 PSI base.
Q: Will it fit my factory VNT turbo?
A: No – this suits F44/F55-frame wastegated turbos only.
Q: Do I need a retune after fitting?
A: If you're raising boost, yes. Boost, fuel and EGTs need to be matched by your tuner.
