Hopefully no permanent damage

Okay guys, so I have a non studded 2007 f250 running SCT livewire ts with IDP Xtream street tune. Earlier today I was going down the highway jumping on it pretty good highest EGT was maybe 1320 for maybe 1 second. When I got home I noticed a little coolant ran down the front spring area from the degas tank. I opened it and relived the pressure. I've driven it around a little since then (no hard throttle hits, just driving normal) haven't seen any more coolant under the truck since. My question is, could I have done any damage. If not what could it have been doing that for. Has anyone else ever experienced this? All temps looked good too.
Thanks Brent.

Could have just been some minor puking. How full is your degas bottle? It should be about 1/2"-1" below the full mark. (Mine is closer to 1" below). If I put more coolant in there, mine will puke it out.

What all is done to the truck modification wise? Also the 1320 EGT's is nothing I have hit over 1900* .

Try replacing the degas bottle cap with a new updated one. They are only $5. Also make sure your coolant level isn't to high. The new MAX line is the OLD MIN line.

Another thing is what are your EOT and ECT??

I am hoping that it was just a little minor puking, what would make it puke a little? I've never seen it do that before. I will have to look again to see where the level is I don't remember. EOT and ECT are no more than 5 to 7 apart at any given time. Thinking maybe I should get a new cap just to be on the safe side. SCT tuner, cold air intake, and turbo back 4 inch MBRP exhaust are the only mods.

You can usually run the temps up pretty high as long as you don't hold em out too long. Just because the "EGTs" are 1900F, doesn't mean that the pistons are over 1200F (point at which most aluminum alloys start melting). Doing a WOT run from like 30-100 mph is pretty harmless regardless of what the temps get up to because the amount of time the pistons are exposed to the heat.

That makes me feel a little better, because I usually come all the way off the throttle as soon as I hit 1250*

Yea there are guys who tow heavy and hold 1200+F EGTs all day long without a problem. I understand not wanting to hurt anything, but I honestly don't think you will if it is for just that short amount of time. Of course it would be better if you had studs but either way it's the pressures there as opposed to temps.
