I agree with the both of them. Order a 34mm flapper from TRE (as I did) and pay Raptor to install and port your turbo. You will also want to upgrade to a better o2 housing or have yours ported. I always had boost creep in cold weather. I upped to a o2 housing with a dump and it didn't help. Then, I had raptor put in the 34mm flapper and port the turbo. Now it is all gone.
