Anytime you get more air in the system you need more fuel, or it will run lean causing a rise in exhaust temps. Which ever one of you boys that saw your plugs go from tan to light grey best be sticking a light down the holes or pull your exhaust off and inspect the pistons, I suspect there may be a problem shortly down the road! I know been there done that. Keep in mind there is one cyl that runs hotter than the other, I believe the mag side is the hot one so check both. For the record I run a fuel controller (boondocker) and I love it, cleaned up my sled big time. I pulled my exhaust off last week and looked at the pistons and they look like new. I dont run my temps over 1250 at any time cuz I like to stay on the safe side. Hope this helps.
P.S.
Is that Boss seat on your cat?
