To be honest, my Harley rarely goes into Parade Mode. Usually when we're riding and it's in the mid to high 90's or above, will it limp back to one cylinder at a long stop light. We've riden when the temp is over 100F and it's no cake walk. You sweat just going down the road. Again, the biggest improvement was the richening up of the fuel/air ratio with the TTS tuner.
