My 04 has a bassani x pipe with 2 hi-flow cats, thinking of switching over to a mac prochamber but will i need a new tune or will it not affect my current tune?
New midpipe new tune?

Your tune will likely be fine, but there are always things to be improved upon when changes are made.

No tune needed, but you'll get a CEL because of the rear O2's. You can have that turned off in the tune.
The tune i currently have already has the CEL off, im wondering if by getting rid of those 2 cats will it throw off my current tune.
Not if the rears are turned off already.
Like Brad said, you'll be fine. No new-tune needed.
I think every car is different..
I have no cats..o2s on..no issues
I'm using predator hand held performance tune..
I did have mil eliminators when I first did it..from reading it' needed,
low and behold..they caused cell issues.
not sure if it adds hp,but I did notice a better pedal response with off road pipe over high flow catted pipe
