I think you will be able to run a 3.2 with those mods pretty comfortably. Some guys are even able to get down to a 3.0 but would be running less timing and mostly not worth it.

The above is with a custom tune. With a canned tune it's kinda up in the air but some guys on here or other forums could get you pretty close if you have a wideband and some way of seeing KR.
