I'd test the ammo you plan to use with all the chokes you have available to test.
IMP CYL isn't always the most accurate, depending on the ammo, and the actual bore size of the barrel you have.

Factory smooth bore slug barrels generaly were IC choked. So that gives you a good place to start.
I agree with trying other chokes as indicated. Also a reminder to stay with one brand of slug , or plan on spending some $ finding which brand shoots best with which choke.

how much does a rifled choke help? im guessing the slug is not spinning when shot out a smooth bore? seems like it would help a lot if im right.
I assume you have choke on your shotgun now. Must have manufacture name.
Look it up on the internet. Information should be available.

A rifled chock can greatly improve the potential accuracy of your gun.
While helping my gun smith buddy sight in some shotguns the rifled chock guns would consistently have tighter groups at fifty yards, many times with two touching. These were usually three shot groups from the bench.
But keep in mind these are 1 oz chunks of lead with a rainbow trajectory, so don't expect benchrest results.

A lot depends on the slug, too.
There's really no way to know what combination of ammo and choke will be best for your gun without testing.
For example, my old pump shoots about the same at 50 yds with either a fully rifled barrel and some sabo rounds, as it does with the fixed modified smooth barrel and plain ole' Foster type slugs.
Very surprising and unexpected.

My experience was that a rifled tube would noticeably tighten slug groups, especially Brenekke slugs which would print three shot clover leafs at 50 yards.
Don't expect a choke tube to stabilize sabot slugs.
As sabot slugs, full length rifled barrels and rifled choke tubes all became available in the early 90's the NRA tested and published, as did Shooting Times and Guns & Ammo the foster slug/brenneke slug/sabot slugs available. This included the wasp waisted "BRI" (by then owned/made by Winchester) Remington Copper Solids and Federal/Barnes Copper slugs. The results for the tests by these three different sources agreed that rifled choke tubes generally improved groups over "smooth bore deer barrels" for foster and Brenneke slugs but had very poor results with modern sabot slugs. A choke tube used with an older style slug is a pretty good bet on improved accuracy. Nothing I've seen in over 25 years of running a southern Michigan range during the months leading to deer season has caused me to doubt that the NRA and two other shooting pubs didn't get it right.
