Has anyone else experienced this significant increase in muzzle velocity?

I am going to assume that my LNIB XM had an air seal issue that was causing the 330 fps that was corrected when this new hop up unit was installed. There's no way that two O rings alone are going to make a 20% increase in muzzle velocity.
