Default check engine light, wierd engine trouble?

Hopefully someone can give me a clue as to what happened here. I am going to take my car to the dealer Wednesday and find out what the deal is for sure and have them reset my check engine light for me. I know I can reset it by disconnecting the battery for a few minutes, I used to do that with all of my off-road vehicles, but since this is a new car and not highly modified, I want the dealer to check it out for me.

Okay, first off, I drive at around 100mph everyday, and I have taken this curve in question at 105mph several times, but tonight something weird happened. I decided I wanted to push the curve to see how fast I can take it, I entered the "s-curve" at 100mph, and came out of it at 120mph, as soon as I came out, I let off the gas and began slowing down to around 80. Before I got to 80, the check engine light started flashing, the car wouldn't gain speed when pressing on the gas, but the turbo would still spool and the blow off valve would still hiss when letting off. I dropped it down to 4th gear and still nothing, the speedo continually dropped to around 40mph, then all of the sudden, power was back, and the check engine stayed on continually instead of blinking. For the next 3 miles to my house, it drove perfect, I let it idle in my front yard and it was fine, I turned it off, looked under the hood and saw nothing unusual. I then started it back up, still had the check engine light, drove it down the road, turned around and came back, it drove perfect? I've never experienced anything like this any ideas?

Also, don't flame me for driving fast, I'm trained to do it, and I only do it when it is completely safe and I'm the only car around.

No clue but it sounds like it pushed itself into limp mode, dont know if fuel cut from overboost can do this. The key will be what the code is...

Is that new subaru dealership open down there yet? Was it west houston subaru that was moving further west down I-10?

Im really curious...do cops give other cops reckless driving tickets...or do you just make sure theres none in the area when you wanna drive hard?


edit to add:

its possible that, assuming you have the factory uppipe, the ecu detected that the egts were too high and it pushed it into limp mode to avoid killing the cat.

Thanks for the reply, I will find out what the code reads tomorrow and let you know. "Limp mode" sounds about right, although I have no idea what that means, that's just how it was running

Police officers have a "courtesy" policy amongst each other. We know that at work, we are driving fast to get to calls and other things all day, so when we get in our personal vehicles, it's hard to slow down the pace. Most of the time when a police officer stops a speeding vehicle and find out that it's another officer, they say okay, be careful. Sometimes you get those officers that take their job way to seriously and give you a good toungue lashing. I don't write anybody speeding tickets, because that would make me a hypocrite. When I do drive fast, it's when I'm on a long road with no other vehicles around.
