you can make minor improvements by opening up , putting a radias edge on and smoothing out the entrances to the runners and the area behind the throttle body and by doing a throttle body coolent heater flow byepass

JUST DON,T GET CRAZY MINOR WORK ON YOUR STOCK TPI can improve the flow AND GAIN YOU A FEW HP FOR ALMOST NO MONEY SPENT but its going to take a part swap to see huge gains like a HOLLEY STEATHRAM,HEADERS and A ROLLER CAM , PLUS BETTER HEADS WILL PROVIDE
