JET 69188 Powr Flo Mass Sensor Review

There were initial problems with the JET MAF sensor which immediately put my LML Duramax in emergency mode. Called JET to resolve the issue and was told to email customer support. After several emails confirming it was purchased through an authorized retailer. They sent me a new sensor and all the emergency mode issues were resolved. The truck appears to have more responsive throttle response and also increases fuel economy by around 0.5 to 1mpg.
