Depends on how well your car responds to it. I hate to say it, but the only way to really tell is buy one, play around with the fuel pressure on a dyno (with an AF meter, DON'T PLAY WITH IT ON THE STREET....), and see if you get some gains. If you get some decent gains, then it's money well spent, if not, then you have an expensive underhood decoration.
I have no idea if your car could benefit from it. Maybe it will, but maybe not. Sorry.
I know I will need one to get the fuel mixture dialed in. A rough adjustment you might say, then I will use the VAFC to fine tune things.
