Default ECU issue? I need a scooby specialist (Bay Area thread b/c need mechanic)

I don't know what's wrong and don't know who to take my car to for diagnosis. I really want to abstain from taking my car to Albany, and Marin Subaru .. or, really any dealership in the area since they all have bad reputations, from what I've read.

In any case, my mods are minimal (2004 WRX):

straight-pipe CBE, and gutted UP.

I had an atmospheric BOV on it for a while before i got my gutted UP, so I went through the whole headache of the CEL P1314 (I think that's the beloved code?) And, after removing the BOV, I would still throw a CEL for high exaust gas tempatures because of the catalytic converter being twisted into a a nasty blob because of the BOV. Whenever I would drive on long highway drives, my car would begin to overheat after an hour or a couple. But, this problem disappeared after I replaced my UP for a gutted UP.

And, now the recent event: I was driving up to Truckee for a day of boarding, and when I reached higher altitudes (don't know if that matters), or was in about two hours of driving, my car begun overheating whenever I reached an incline, and would drop a bit towards normal whenever I declined. I ultimately pulled over and found all my coolant overflowing in the reservoir. After allowing the coolant to fall back into the system with the car off, I was able to drive the remainder of my trip up the mountain.

Basically now: I can drive long spans of highway at regular speeds and my engine temp only raises a little but is within the middle third. As soon as I come to a stop, or slow down, however, my engine temps begin to spike.

Is this an ECU issue? I thought radiator, at first--but, the cooling cycles .. just not in a regular fashion, it seems. Something else that I'm missing completely?

Also: where in the Bay Area can I take my car? I live in East Bay. So, some place closer to there would be incredible. Thanks for any help anyone has to offer!

Hmm, strange. I thought my reputation was a bit better than "all having bad reputations". If you want it done under warranty, then you'll need a dealership. If not, then I'd second the above suggestion.
