bleed valve set at 10 psi,pod filter/high flow pannel filter with cold air feed if you can, walbro pump,perhaps a rising rate regulator,re tuned ecu.that should set u back $1000 dollars.
Then i would go to free up your stock dump pipe with a aftermarket item,intercooler kits are next to nothing these days,and then a better boost controller turbo smart etc.
You should save your pennies and get a intercooler with the upgrade and a turbosmart 2 stage boost controller.Less than another $1000 and you could run more boost.
HTH..
