You misunderstood my question.
You should log\plot your current performance on a compressor map for example so that you can determine if increasing the cold side is what's really needed. Since you already have @Brendanm on the other side of the pond already running the turbo upgrade you're going to, why not do logs to compare with him? That should easily tell a story of how these two setups differ.
Let's assume that your compressor CFM is your limiting factor @ 4k rpm. Will you have sufficient fuel to support more air? Will your intercoolers be adequate for more boost? Are you going for more boost and flow or just more flow at the same PR?
Unless you have some data points from your current OEMish setup, you're just making assumptions. What if EGTs are you limiting factor at the moment?
