Yes the tiller should be the same, but it wouldn't hurt to check. The Limb bolts do not affect cam timing. To check to see if they kick over in the same time (starting the valey) then hold the bow as horizontally as you can and draw your bow. Look at your cams while you draw. I use this method because I usually am by myself when tuning. But you can also draw you bow normally and have someone else check it out for you. Im not sure about having the top cam before the bottom cam. I have never heard of this. Most people want tiller to be the same but it is not as important as other things when tuning.
