V2 center diff problem. Truck weighs 6.5 pounds, and during take off or hard exceleration on assfault, and turf my diff is slipping. I have it assembled correctly, and the clutch spring is completely compressed. I'm running 9 pins as recommended for a high bite conditions. Am I going the wrong way with this given the high traction surfac I'm running on. Seems more pins reduce the diff action. My guess is that it's such a heavy truck on a high traction surface that something has to give. Any one else come a cross this? Should I switch back to the VTS?

I'm running a MMP 1410 setup geared 62/14.
