Tin, on the JeepSRT forum there are a couple guys that have a ton of stroker tuning experience. One of them is Diablotoona.
Not trying to be a Negative Nancy, but remember perfect is often the enemy of good.
Good luck with the tuning.

Tin,
You may in fact need a tune. I've read (can't confirm but makes sense) that when you remove the catalytic converters the reduced back pressure results in a rich situation.
Let us know how it goes.
