Speed density uses the manifold air pressure, then looks in the computer for the amount of fuel to use. The MAF system doesn't rely on a set of fixed parameters in the computer like the speed density does. If you have more airflow than the highest parameter in a speed density setup, the computer doesn't know how to react. Therefore the engine runs like crap in a worst case scenario. Mass air will adapt to changes made to the engine better. This means it will milk more power out of every modification. -------------------- "Horsepower is how fast you hit the wall, Torque is how far you take the wall with you." 1989 bronco with a 8 inch lift...GONE 1972 camaro split bumper....GONE 1994 bagged and shaved s10....GONE 1989 mustang....GONE whats next?

Mass Air - The computer uses a sensor to measure the MASS of the AIR to measure the the amount of air coming into the engine. Speed Density - The comptuer uses a sensor to measure the pressure of the air in the intake manifold to measure the the amount of air coming into the engine. Posts: 2373 | Registered: Jun 2000  |  :
