Are there PCIIIr or USB maps specific for use with an ATRE?I was led to believe the PCIIIr eliminates the need for a TRE.Is this not true?I am trying to figure out what electronics to start out with on my bike.I am fortunate to have places to hit the top-end limiter from time to time and it is getting frustrating.However,I also have other mods planned,such as exhaust,airbox,etc, which may require something along the lines of a Power Commander.Thought I understood,but now am not so sure.It's an '03 by the way.
