Replacement/uprated actuator req'd - Any recommendations?

Was close to finishing my Single conversion but have hit another bump in the road to completion!

Can't go above 1.2bar due to the actuator not being strong enough to keep the (internal) wastegate shut, even with the boost solenoid at full duty and the actuator fully adjusted it barely reaches 1.2bar and probably doesn't spool as quick as it could.

Does anyone have any recomendations/past experiences with any company that can supply decent actuators?

Would I be needing to find out exactly what turbo I have and find a matching actuator & bracket or is there someone I might supply measurements of my current actuator? Luckily it has a straight bar coming from it and not a bent one like some I have seen.

Thanks in advance for any advice/experience you could offer!

No one had to get one of these before?

Been looking around the net and can find plenty of them for cossies so might have to measure mine and ask on their forums.

Why dont you just change the boost control solenoid? Maybe a big company like Turbo Technics or CR turbos can help?

Boost control solenoid is fine - brand new AEM one fitted this week all controlled by the AEM EMS

Even if the solenoid is fully open it is not able to stop the wastegate opening, it's just not strong enough

The wastegate opens early preventing quick spool and at 1.2 bar it is overwhelmed, opens and prevents it boosting any higher.

Will check both Turbo Techniks and CR Turbos - many thanks for the suggestions!
