I have been over boosting since my last turbo (28psi) and on the new turbo Ive seen it hit 30psi. Nothing else has changed. I am affraid of killing my turbo / engine so I want to bring the boost to a 24 peak and 19-21 hold.

Does anyone have experience with Manual Boost Controller on these engines?
I have read people use them to up the boost, will it work for lowering boost as well?

I will be running boost logs to see if the boost is higher than requested, but I suspect everything is working as requested as I have no CEL or indication otherwise.

Any info on this topic would be helpful.
