If Suneil wants more power he needs to change the AR on the turbine side. If you look at his graph you can see the exhaust flow is too much with those Kinger heads for the .63 he has. Changing to an .82 could net him 50 more hp but with a slightly later threash hold and a bit more lag. A 3L should certainly have a .82 and probably a 60 trim compressor as opposed to the 57 he has now.
