Hey MD, what cam are you running in your car? Are you running the larger throttle bodies?
I am only asking because as I am sure you already know the is far more power to be gained there than with the Blower. You mentioned you had done everything so I am just wanting to find out what road you actually are going down and if it works.
If you haven't taken the more obvious way of gaining power and your talking about digging deep into your pockets, I have some Swamp Land you might like to purchase.
