An intercooler will help a ton also over the entire powerband.

No need for more fuel just yet as you are still plenty rich under load.

3" downpipe, NPR or Ebay IC and turn the boost up to 16psi. Those alone should put you near 200whp.

The down pipe is where the exhaust is still extremely hot so the extra volume will allow for better evacuation.
