You can prolly get by with out it for a while. The motor is going to run really rich if it's anything like mine was. Just by install the TFS heads my gas mileage dropped nearly five miles per gallon. Once I got it tuned, my fuel economy went back up and it ran like a scalded dog!
In the end I had TFS heads, TFS track heAt intake, 65mm throttle body, 75mm air meter, complete accel ignition, full length headers, off road xpipe, magnaflow cat back. Car was a beast.
