I have a 80 mm mass air sensor and computer chip bought from Powertrain Dynamics in California that has been used for a little over a year but still in great shape. It is calibrated for 24 lb injectors and made to fit 5.0 liter mustangs with mass air. I have the spec sheet for it from Powertrain Dynamics also. Asking $150 obo for both. E mail me at [email protected] if interested.
