The PINK cam is the ""least"" aggressive off idle of the entire selection of pump cams!!!!!

I would suggest a white or red (very similar to each other and twice as aggressive off idle than the pink cam.) cam on position #1. If that helps but not all the way, then I would suggest the Orange pump cam which is more aggressive than the white or red cams and it also has more overall pump volume (which you may or may not need), But for testing purposes, I would leave the 42 in there and just swap out pump cams for now.
Note: you will need to shorten the pump arm screw to install the larger pump cams. Maybe 1/2 turn before insalling the white or red cam and then once the cam is in, readjust.
