have never tuned a T-Bird before, but I have seen the octane pin you are referring to. However, I don't think the Mustangs have this. I mostly tune 5.0L, but my '01 GT I tuned using an Autologic chip. I bout the car so I could tune an AODE, so far I have gotten the car to 13.89 with the chip. A gain of .53 seconds in the 1/4. The car shift like a rocket, but spins real bad into second gear. At one point or another I think I have had my fingers into every aftermarket chip and system there is, but I have never messed with Superchips. I have always heard they have limited editing. We built a '92 LX with a 331 and a 38psi blower and it had serious pre-ignition with a Superchip. After literally pitching the Superchip and tuning the car with a PMS it ran great. I ultimately did the final program with a chip.
