Overheating what havent I changed?

While you're waiting for the undertray to arrive, you should be running 100% distilled water plus a bottle of Water Wetter, and disconnect the signal wire to your ac compressor. Once you do that, turning your AC on (and having the cabin fan control in 1 or higher) will turn on both your fans, which should bring those temps way down at low speeds, and may help at highway speeds as well.

I am already running fans in paralle. I followed hakunas guide over on m.net. it help but still. I bet the undertray will fix it because Savigton said so. Just a waiting game at this point. I also ordered stage 2 fan shroud from fm this morning just cause. I read lots of reviews and to be honest the mishis blow lighter than the stock fans. Originally I only got them because when I was na I couldn't fit the intake that well on my 91 at the time. The fans were ok most of the year when I was still na. My friends gonna buy my mishi fan.

I don't trust cheap aftermarket fans either. I took the time to trim my stockers so they'd fit with my Koyo55 & FMII, after being less than impressed with the Partzfinder strap-on fans.
Try the AC trick though - just disconnect the compressor trigger wire, and your fans will turn on from the AC button.

I do find it funny that my 93' at 10psi in 118 degree weather with no undertray, 1 fan, koyo radiator doesn't go above 180 on the highway or in stop and go traffic even when pushing it hard.

I believe the consensus is that pure water provides superior cooling performance, but that for street cars, adding some antifreeze is necessary for corossion protection.
In my non-turbo '90 (with no undertray, stock radiator, etc) I run appx. 30% antifreeze.

How is it possible to use 100% water and then add water wetter on top of that??? Your radiator would be overflowing and ****!!!
If you want the ABSOLUTE BEST COOLANT POSSIBLE then fill that ****** with 100%compressed liquid ammonia. No ****.
But in the real world, water is the best coolant because of its high specific heat (liquid ammonia has a 40% higher specific heat at 212* :P ), water wetter does indeed add a level of corrosion resistance, but the primary purpose of water wetter is to break/reduce the surface tension of water which results in greater surface area contact between metal and water at the molecular level...apparently.
Edit: Put your undertray on.

I wonder how many people actually use the undertray. I'd imagine a lot of turbo'd people do not with the extra cutting required (horrible excuse I know). I fully "intend" to run mine as I know the benefits. But I bet there are a lot of people who "intend" to put it back on too.
