Default Re: Guesses on my rattle?
The backfire in neutral is normal burning of the fuel rich spent gasses from the motor. If you rev up and slowly rev down you will probably not hear it. Mine is running very rich as seen on the data logger in this condition, leans out TERRIBLY on 18psig + boost so its going to have the ECU sent back to the Doll Hospital for a tune shortly. Currently apart for gauge pod installation due to the lousy cold weather.

Enjoy, W DY
