Chip

Chip is perhaps one of the most talked about tuning in the EEC based Mustangs. And yes I had a chip on my setup and here's what I think of it. No matter where you get your chip burned, I recommend it to be done on a dyno with a wide band oxygen sensor in tact. I had my chip burned by Matt at APE based on a dyno session at Danielson Ford in CT. In my case, I had S-Trim, Headers, and Catback at the time of the tune. The base run recorded 277rwhp / 315ft#. With the chip, it went up to 299rwhp/329ft#. The bottle neck on my setup was the stock cats and MAF.

  • The chip will do what it is advertised to do. Period.
  • Keep your FMU: If you're going with the chip, my advice is to keep it, and here's why. Surely, if you're going with the larger injectors, go ahead and ditch the FMU. But with stock injectors, FMU with a bleed valve will be very helpful adjusting the fuel pressure at the track for the gas you're running.
  • Keep your Timing Retard: The chip can also control this for you, but like the FMU, you'll have more tuning tool in your hands. When you get the chip burned, set the knob at like 1/2. Use this setting as the starting point. On the street or at the track, depending on the gas you're running, move the knob up or down for your best setting for that specific day.
  • I also liked the fan control and the rev. limit changes the chip can provide for you.
