Depends on what you want to do to your car. If you are keeping it stock, the extender seems ok. But all it does is adjust air/fuel at WOT, supposedly gets rid of the ignition retard at shifts, and upps the rev limiter. If you are doing heads, intake, cam, 347 kit, look at the Ford EPEC, eec tuner, or Anderson PMS. I would NOT recommend swapping in an earlier computer. I did it with a Pro-M PIH and it didn't solve a damn thing for me. Now I'm trying to do some research in the EPEC, eec-tuner, and PMS systems. Actually, it's between the EPEC and PMS. Between the cost of the PIH kit, MAF, and computer, I coulda had the EPEC.
