Wastegate rattle fix redneck style

This update will eliminate deceleration rattle, but not acceleration rattle.

How is everyone's still holding up? I've learned to deal with my actuator rod rattling, but it would be a convenience to have a BMW that doesn't make tinny noises. My wastegates aren't rattling and I can clearly see the oblonged area of the actuator rod that is causing the rattle.

So I've had the wastegate rattle both accel and deccel. I did the spring fix and it did helps with the deccel rattle quite a bit but now I get an Engine Malfunction reduced power signal when I get higher in the RPM range and boost around 5k rpm. I also noticed my power output is less all around too.

I'm torn because I love that it makes less rattling but it kills me to have essentially stock power and get these error signals when I get on the throttle.

Anyone with experience in my shoes have any ideas. Any input?

I'm thinking of just taking the spring off and dealing with the rattle

. I miss the silly high power. BOOST!

I have brand new stock replacement turbos with the upgraded wastegate components and the car was rattling like crazy. I went into the JB4 FUD options (click on the "bits" tab under user adjustments) and there was an option for "alternative wastegate position" which set the FUD to 128. I went to setting 10 on the speedo and set the RPM setting to 5 and the rattle is gone. Boost response is great too.

I think the jb4 settings just needed to be tweaked.
