didn't mean to derail the thread by my comment about the II EFR turbo kit.........But with all the fuel, air was going to need to be addressed sometime sooner or later. Only thing I don't like about the 9180, the only way to get an internal wastegate is to run a T3 turbo flange. We all know these larger displaced diesels need the T4 to keep drive pressure and EGTs down. Maybe the wastegate with proper tuning will allow the T3 to function, but I think we can get more out of the turbo running the T4 flange.
My drive is 40 boost 28
Not terrible
I have some videos if I can post them
