Tune or Not????? Ok everyone i just installed a racetronix fuel pump in my 96 formula bird. My question is should i get it tuned or not. Cause im pretty sure this performance pump put more fuel in then the stocker. so do i need to get it tuned to make it so im not running rich. Please HELP!!!!! i got the pump, the wiring harness, and the booster connector. Thanks in advance.

I'm assuming your Racetronix kit cam with a Walbro 255lph pump. While that is more efficient than the stocker, the same fuel pressure regulator is being used to regulate the fuel pressure, furthermore the fuel delivery is controlled by the computer via pulsewidth. Basically, no, you don't need a tune, and you won't run rich.
