Upgraded Boost Solenoids?

My car is significantly overboosting in the low to mid range (19psi on map 0).

This has been happening before and after new turbo replacement.

I now think this may be the boost solenoids playing up - I'll be testing them tomorrow. Just wondered whether I should buy OEM replacements or whether there are some recommended after market options to consider.

I'm FBO, stock twins with Meth.

Ok great, I'll go OEM.

I know that there are aftermarket boost control solenoids available for Subaru's and EVOs etc which claim to lower WG Duty cycles etc. Just wondered whether there was anything similar on this platform.
