Hey, Elvis! Howya' doin'?
The GI pro with ATRE (advanced timing retardation elimination) tricks the ECU into thinking that the bike is in 4th gear (where there is no timing retardation) all the time except when in neutral. The result is that it does away with the retarded timing in gears 1-3 (there is none in 5th gear), having the same effect as if you removed the secondaries. It also does away with the speed limiter in fifth, I believe raising top end on a stock non-Tourer from about 135 mph to about 150 mph.
