I know the S550s can’t do the cam chop but is there anyway to get it to chop? Not tune chop.

With dual overhead cams and variable valve timing, there's no need for the Coyote to have a choppy idle. It's literally a best-of-both-worlds scenario. You can have good low end torque, and still breathe at high RPM. You might get a little bit of chop with aggressive aftermarket cams, but your car won't be very fun to drive on the street any more. That's why some people run a ghost tune to get a noticeably choppy idle, and at that point it's just like the BMW kids that run crackle/burble tunes - noise for no reason.
A single cam engine like the LS will chop with an aggressive cam because of the design limitations associated with having only one camshaft. You have to run aggressive lobe separation angles and high lift, which leads to at-idle misfires which give that choppy idle.

Keep in mind that "Tune chop" or "Ghost cam" is really your cams just with the VVTI system rolling them to the highest duration for high RPM breathing. Its a real cam, and performs like one with larger LSA and longer duration!

I had a magic stick 3 camshaft in my old ws6 fbody. Pair that with a very stiff race clutch and it's the perfect storm for absolutely zero drivability around town. If you ever experienced a true choppy cam you would appreciate regular cam specs at idle. Much better. Anyway, a ghost cam tune is the only proper way.
