Ok I installed my 4.0 TB. 
I did it at work and didn't realize until I got it all apart that i needed those safety Torx bit to remove the AIS. So I left the 4.0 Plunger and housing on the throttle body but DID swap the TPS. 
I installed it on my Wrangler and there is not Idle issues. I haven't driven it down the road yet but sitting at idle and reving it in the parking lot it seems fine. 
Any comment on this?
Thanks
