High Exhaust Back Pressure

[blacksmoke.r.us]

Swapped a 17+ turbo into my 2012 and noticed high exhaust back pressure. 20 psi until about 1300 rpm when it stsrts to build a little boost. My 2011 with stock turbo sees about 3-4psi of back pressure. I didn't change the tuning with the 17 turbo but I read I could run as is. Anybody have any experience with this?

I think you should try a tuning revision.
