Stock Header
ATI 2% Harmonic balancer
17% supercharger Pully
Oil catch can
I have plug in tuner on the way(from this site)

Any thoughts on what I should do next?

Thanks
To get an accurate power output from your car, you should take your car to a shop that can run a dyno test.  This will give you an approximate power output.  You should also get an air/fuel reading at the same time to make sure your car is running 'safely'.

With a 17% pulley and a 2% crank pulley, you are already pushing the supercharger beyond the safe limits at red line - so I would recommend you be careful winding up the engine.

Since you are running high boost, you might consider an intercooler upgrade to reduce the intake air temperature. This will not only reduce the stress on the engine, but it should also improve performance.
