I wouldn't do it, you just need another pin for you fans and rework the efan harness so the PCM can control High/low functions instead of AC wire crap...

Oh forgot about that.... Is yours still running hot? Maybe you could just do the BB mod.... Do a search for it... It will cool it down a few degrees and it only costs the amount of a single BB...

I believe that closed loop occurs around 137* or something like that, so you will have closed loop. I have a 160* stat, but I'm tuned for it and I have my efans set to come on at 180* and off at 173*. One day this summer though, my factory temp gauge went up over 200*, with the ac on when it was really hot out. I haven't seen a temp like that out of my truck since going to the cooler stat with efans, so I was a little surprised. Not sure if it would have come down if I had time to drive it more though, as I reached my destination and turned the truck off at that point. (I doubt that it would have come down since the fans were already on and also running on high when the compressor kicked on).

Besides allowing you to run more timing, the cooler engine temps will in turn allow the trans to run cooler also, which is always a plus

but what AFR were you actually commanding, that as my point in my previous post, it should command a richer mixture, the same as it does on warmup...

I don't think so. Since alot people warned me and dont swap to lower stat. BEcause it will mess up with PCM. I foget what it call. By timing adjustment itself. Without tuning that is the point. I would stay stock one.
