DCC equipped GP30's

[thud]

I have 4 of these locos. Three of the 4 run just great. However the 4th one runs very slowly using the same settings as on the other three. Engine runs good, but very slow compared to the other three. Any suggestions?

Reset all the CVs on the loco that isn't running the same. Or if all else fails, provided you bought it from a legitimate dealer you can send it in to Bachmann for replacement.
