Spark Plugs

Just wanted your thoughts on spark plugs.
This last week I was out in the Big Horns and had some starting problems with my '07 turbo Apex. It uses a Attitude fuel controller. I was using CR10EK plugs gapped to .020" It was EXTREMELY COLD this week.
Friday morning- it was like -10deg, in the morning. Sled started, barely, sounded like it was only running on 3 cyl for about 5 min, just let it idle and warm up, finally started firing correctly, ran fine all day.
Sat. morning- -10 deg out again this morning. Fired real hard again, ran for about 20 sec, died. It did this about 4-5 more times. Then nothing, couldn't even get it to pop. Tried it on & off all day, nothing, didn't really care it was New Year's day & I wanted to watch football anyways, I'll worry about it tomarrow.
Sun morning- Drove down the hill to try and find new plugs. No one had CR10EK's or CR10E's , all they had were CR9E's. I'm pretty sure this is the stock plug or close to it.Wanting at least salvage a little riding on this trip I bought them with the intent to just turn down the boost and ride. I put these plugs in and the sled fired right up. I left the gap at what they came out of the box at(looked like about .030")
Sled ran fine. I ran it all day Monday on these plugs, running about 8psi. No sputter, spark blow out, or the like.

Now the big question: How crazy would it be to leave these plugs in. I must say, I'm getting really sick of taking this thing apart. If I just planned on running around 11-13psi max on pump gas do you think I would be OK with these plugs? Or should I just bite the bullet and change them out?
Also, theoretically wouldnt the CR9E'a start easier since they are hotter?

Sorry for the long post.
 
I think at the boost levels you are running you will not likely see any blowout. Its the guys trying to run above 20 that are having troubles. I say go with it as long as she starts for ya.
