It absolutely WILL maintain the speed you set but it may scare the******out of you!!
AND, use more gasoline-- high RPM= more fuel consumption.
Most efficient gasoline engine is at lower RPM, higher throttle position-- less vacuum means less HP lost to "pulling the piston down". Nothing new here-- BMW pushed this on their "e series" many decades ago.
Many of the tuners delay downshifting until higher throttle position/more speed drop is reached. That is the way I would want mine set up as well.
