i had it tuned down to 22psi where the wastegate can handle it. i’m going to address the wga again when i eventually buy/install a manifold.

Do they make a wastegate with a bent rod that will hold higher psi than 22?

according to ron from whoosh, this wga can handle over 30psi with the spring pack installed from the factory. that would mean my issue is most likely in the preload.

The only way is if you buy a spring kit and do it yourself. I've only seen them go as high as 22psi*

It looks like this wastegate only goes up to 22 psi
