I have full 20psi boost at 4400rpm (not just the boost but the power is very strong from these revs onwards, its average power is flat out unreal from 4k to 8k rpm very flexible for a 13B engine) the whole set up is more around mid range power rather than anything to do with top end

I could improve it even more by dropping the exhaust system pressure by not running a catalyst, but I like it legal and the sound is really nice too in note and volume.

Well I am impressed that you are running a cat converter. This is something I will have to install this year. Just surprised you do not burn through those cat converters. Do you have a air pump attached to your catalyst? Do you have to pass emissions?
