My insight likes to lug the engine to 80% before it revs or changed cvt ratio and in sport mode only lugs the engine to 60% according to the SG2.
Of course it uses the VTEC to delay closing of the intake valves on the compression stroke to lessen pumping losses, but it feels like you got a vacuum leak.
In manual mode it will let you do what you want in regards to load up to redline or near idle, otherwise it goes up or down a predefined ratio of the 7 it gives you.
