Does the moco stage one d-load move the rev limiter to over 6000 rpm's?
I have search a bit on my new to me '05 Ultra and I don't find a tuner but it has Rinehart true duals and high flow A/C with no backfires. It does rev to over 6k.
Just trying to learn a bit about my new ride.

 

It's likely flashed from the dealership, if it's running good enjoy, the previous owner spend some cheddar on the mod and upgrade......It would be great if you could hook a laptop to the ecm and see what the flash did, but sadly no dice. See if you can get a dealership to run the VIN and pull some records, if it was done at a dealership (it was) you might be able to research the upgrade for details. It is after all your bike now and have the right to know.

 

More than likely your bike has the Stage 1 download. Yes, it raises the limit to 6200.
Try TUCCI's suggestion to see if dealer can help.

 

Stage 1 download ups the rev limiter to 6250, With the AC and the pipe & you are running well, I would say it;s been done.
