Replace the factory rubber hose that runs from the wastegate actuator to the factory pipe that runs to the throttle body with a hose with the same dimensions.

the factory hose has a metal restrictor inside it that limits the boost to ~7psi.

with the new hose you will boost ~10psi

this mod cost me 2 dollars and my car is significantly faster.

i didn't believe it either at first until i cut open the hose. there is a thick metal hose type dealie inside the rubber hose that signicantly limits flow through the hose. it's about 8 inches long.....THAT'S WHAT SHE SAID
