Differance between 1450 and 1340 program

I had a customer come into the shop today with a 2000 Electra Glide, they had the bike at another shop and could not get it running. A little history, the previous shop shorted out the ECU and it needed to be replaced, the customer bought the new ECU and HD Pro-Tuner software. They loaded in the 1450 Standard map, the fuel pump turns on when you first turn on the ignition, it then turns off after 5 seconds, then you crank the bike the fuel pump never turns back on, if you try to start the bike within the first 5 seconds when the fuel pump is on the bike runs but then shuts off when the fuel pump shuts off.

I spent quite a while trying to troubleshoot the bike but could not seem to find any problem other than the fuel pump does not come back on. Out of desperation I loaded in the map program from the 1340, now the fuel pump does the same thing, it turns on for 5 seconds and then turns off the difference is now when I crank the bike it starts and seems to run fine.

My concern is running the bike too lean with the 1340 program in it, so I'm wondering what is the difference between the two different files and why does the fuel pump turn on with the 1340 program and not with the 1450 file, the motor is a 1450.

Any help would be appreciated.
