I have more experience with 300/400 compounds. I'm diving into 400/400 compounds and am wondering if a 472/83/90 is a good idea to run with a 491/96/1.32. truck has 250 overs. And how tuning on a 2005 Cummins. I'm wondering if that .90 housing with the 83 wheel is gonna be my bottle neck or create any issues. I use a 1.0 housing on my 369 but didn't know if it matters as much on s400 frame turbos
