here are the steps:
1. Uninstall the piece of crap performance module
2. make sure the mass air flow sensor is straight up and down
this should fix your problem.
In HVAC terminology, a diffuser's neck velocity is defined as the velocity of air traveling through the duct work to the air outlet or inlet. The difference of the face velocity is this is a measurement of fume hood performance.
muzzle velocity is the velocity of bullet and recoil velocity is the velocity of gun.
linear velocity= radius* angular velocity
Velocity includes a Direction.
Velocity is speed with direction
Speed is magnitude of velocity, also velocity possess direction.
Acceleration is the rate at which velocity changes.
Both have mileage.
velocity = displacement / time taken
Acceleration is the rate of change of velocity.
Velocity includes direction. And it's the 'difference', not the 'distance'.
Acceleration is the rate of change of the magnitude of velocity and the direction in which the velocity changes.
