tps

E - what I would do (note that I said "I" in case S&2B's comes in here later ) is do the install and simply check where your TPS is baselined. It should be real close. Unless it was off by a country mile, I'd leave it myself (ratcheting keeps a reading within adaptive-control in spec).
It is nice to see where you're starting off though (I know you're a pretty particular/meticulous guy). A personal E.g.: I've never adjusted the one on the '88, but I know it sits at just under 1.20 volts; that's fine with me.

Just MHO. Good luck.
