@david85 Well just remember boost psi doesn't exactly equal flow or more importantly efficiency. For example I had a friend with a 5.9 cummins in a dodge that was pushing near 40psi with the stock turbo. When he switched to a larger more efficient turbo he actually lost psi down to 32psi, but gained power. It's all about having a properly sized turbo not just high boost numbers.
