does anybody run with out the under tray
So no one else noticed the understeer? Well, in my case, for whatever reason, when I took it off I couldn't go NEARLY as fast on the on and off ramps to the highway. I've been driving these ramps for three years on this car and it's a huge difference.
I took mine off when I started modding my car (like a month after buying it). Its been off ever since. I've never had any issues with it off. I still have it though in case I need to put it back on for whatever reason.
leaving the under-tray off also makes it allot easier to snag your lip on things and tear it off.. i leaned that the hard way snagging on a stick backing up.. but i still dont have mine on, the car spends most its life jacked up, ive had mine off for 20k once my dump pipe was put on.
I don't like running without it, but I have for short periods when required. It's not trimmed to fit the FMIC and the dump pipe. I'm actually in the process of making a carbon one to replace it and fill the gap left where I had to chop it for the FMIC.
The undertray is there for many reasons, only one of which it to keep rocks and such out of the engine bay, but that's minor. It provides down force and much needed cooling to the transmission, TC and brakes. That's the main purpose. Removing it will increase drag, lower fuel economy, affect handling and lower cooling ability of the parts mentioned. Keep it on.

PUT IT BACK ON!!!! I took mine off for a clutch job and lagged on putting it back on. Biggest mistake of all time. 
Crushed my oil filter from hitting something on the freeway. This picture and the $9K bill for a new block and built(stroked to 2.3 since the motors out) motor should be enough reason to go put your undertray back on. TODAY!

eh, I lost mine in a bit of unlawful mudding-about.
Over 50K miles later, no bad business.
bent a downpipe from flying over a RR cross way too fast (reminded of the Ken Block ramp crash) but the undertray would not have prevented any impact.
What it is good for is keeping rocks, mud, stinky road dirt out and off your block. ( dirt and gravel out of your door hinges for the wheel wells.)
If you keep it, lovely. If you break or lose it, no worries.
