Clean out I/C
Install 160* thermostat. Just buy a 160* chevy unit at your favorite parts store and trim to fit.
Block off (or loop) throttle body coolant lines. I like to block them off with the little colored plastic tacks. Just snip off the tack part and insert the plastic piece into the line. One on each hose for that "stock appearing look"
Fits inside the hose nicely and blocks the coolant from reaching the TB.
AC R43TS plugs gapped at .032"
Get a set of Red Armstrong's plug wires. (~$20).
Check for vacuum leaks and check all one-way check valves. It's important not to lose valuable boost the turbo is having to create. The more you lose, the warmer your air charge will be to run the desired amount of boost. The only real way to hunt down air leaks is with a Mity-Vac pump. 'bout $40.
Get an ATR check valve and install it before the PCV. I have never seen a PCV that will hold ANY boost. Even brand new.
Get some GSCA club valve springs.
Bad wires, wrong plugs, dirty IC, air leaks are all things that can go unnoticed and end up being detrimental to performance.
What kind of injectors and chip do you have? If you have stockers or blue tops go with a thrasher chip.
ok,ok, so most of this stuff is not "free", but it's the little things that add up.
