One of the best upgrades for a stock turbo Fiesta ST. Sadly I sold my car before I even opened the box due to changing life circumstances. These retail for $160 new plus shipping, I'll sell it to you for $125 shipped in the continental US just as it was sent to me. Get a sweet discount on a nice high-quality piece of engineering.

The TUNE+ upgraded wastegate actuator is one of the most popular upgrades recommend by our customers, after a tune and intercooler. The benefits are far greater than what you would get from any other bolt on upgrade that follows it. This actuator is manufactured by Turbosmart Australia exclusively for TUNE+, using our proprietary spring system and a few other small design tweaks. The standard off the shelf Turbosmart actuator is a great upgrade, but needs a few changes to allow it to produce the below outlined benefits I was looking for.
- Consistent, and more predictable boost
- Cures part throttle boost surging
- Prevents boost spike during post-shift recovery, which can cause throttle closures
- Increases high rpm boost levels by 1-3psi *
- Flatter torque curve
- 10-15whp increase across the curve (Not peak)
