I have the BTG and like the look of it, but Cal is right, for pure horsepower there isn't 10 hp difference in the various systems.
Now my soapbox!
The turbo engineers tell us that if we want to make a significant differance in the efficiency of the turbo (POWER), the larger piping needs to be right off the turbo (check the 1.75"down pipe and cat that come stock)....replacing these items with 3" cat and downpipe WILL make that great big difference you are looking for!
