I installed my dalton kit today. works great holds 8000, may drop to 7950 for a second then back to 8000 all the way. It wasn't holding 8000 before and wouldn't shift back right. when i removed the primary i found that one of the arms on the weights , was stiff, there was some carbon on it and, it was just shimed to tight from the factory ( washers was to thick) , i cleaned it and it moved better but was still stiffer than the rest. with a little work it would have ran like it did when i bought it. yes the dalton does run better, and i'm happy with it. but if anyone else is having issues you might want to check/clean the arms.
