| i installed the shim kit on my 05 LLY and it only took me 1.5 hour to do every thing and out of that hour i spent 45min.s getting the valve out of the fuel rail so if you do this kit make sure you use the right wrench or else you will strip the valve nut....it took care of my 2k rpm limmiter on a hot tune but it will kick back in at 130mph...
