Yes its a very worthwhile mod to do over the factory item.
Only down side is you’ll have to get the car re-mapped preferably via a Cobb handset which will save your FPM375 map.
Its a turbo off jobbie to fit. their are 3 spring rates from 7lbs, 12lbs or 14lbs.
12lbs is the most commonly used, Mountune USA use 14lbs.
What they say:
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
– Increases high rpm boost levels by 1-3psi *
– Flatter torque curve
– Horsepower gains after peak power (some vehicles will see a peak power increase as well)
RS Edition.

The rest of the “M” maps suck
