Awesome. I am glad to see you are monitoring trans temps and It appears you did the proper research! I recently had to do my UIM and found this (see pic) Keep an eye out the runners were warped to hell. I have a much better powerband now. Dont forget to check the EGR passages in the UIM they get really brittle. Sorry not trying to threadjack just trying to give some friendy advice.
Dan and some others over on the other forum blocked the coolant passages from the LIM to the UIM. Maybe that would give you a touch of heat in the plenum kind of like a free WAI?
New runners on top.. See the difference? The photos dont show how bad they really were. Some were totally deformed and not sealing to the LIM.
