Hi there, I have a 1996 Mustang GT. The owner before put long tube headers, H-pipe (no cats), and Magna-flow exhaust on it but left the rest of the car stock. He put the O2 sensors right back in without changing anything. My check engine light is always on saying I have O2 malfunction etc... depending on the weather and the moisture in the air, it seems like the engine is holding back and some what sputters. If I put the peddle to the floor, it will snap out of it. Is this an O2 sensor problem? Would the SCT X4 Tuner fix this?

The SCT X4 with SVE Custom Tune will indeed eliminate the Check engine light and PCM codes for the rear O2 sensor faults. However, the drivablity/sputtering is likely stemming from something else. You'll want to check and the overall "tune-up" of the car. Check and replace as needed your coil packs, plug wires, spark plugs, air filter, and fuel filter. I'd also suggest cleaning the MAF sensor element using electrical contact cleaner.
