So I have the second TMAP sensor installed and wired temporarily, need to shorten the new wiring harness, remove the D-box harness and clean it up a bit.
Seems to be operating normally so I took a short drive and grabbed a log if someone wants to have a look.

I'll put together a list of materials I used to put everything together and where I got them if anyone is interested. For the wiring I basically took a 4 pin extension harness and spliced the appropriate wires from a 4 pin pigtail for the second TMAP which only provides MAP signal and the original in runner TMAP provides IAT.
