Hmm, did you modify the small section of pipe from the turbo flange to downpipe 1st bend when you added the additional bung to the DP?

My Spec 90 has a velocity stack shaped piece off the turbo flange...

Which I will be cutting off and welding on a larger pipe since I am going to "P" trim exhaust wheel on my stock hybrid and its internal diameter is 2.55"

So, how you liking the boost creep

 

I havent modified anything on the DP except for the extra bung.
