I am looking for some help in improving the performance of one of the Atlas GP9 Torpedo Tube locos that I purchased last year from Tony's Trains. I had the decoder installed. Every other decoder equiped loco the I have including a Bachman 2-8-0 begins to move at speed step 1. Even most of my non-decodered Address 00 locos move at 1-3. The Atlas GP doesn't move until about speed step 31. I tried reseting the decoder to factory default but it remains the same BTW I am in n-scale and use the Digitrax Super Chief - radio version. The decoder is a Lenz product. I haven't tried to do a speed table yet until I get the engine to start moving when I turn the control to 1. Any thoughts or Ideas.
