Custom Tunes with Champion 7879

[Alcohol5LT]

Hey ya'll,

So I got my customs tunes a couple of months ago, I absolutely love the 87 performance turn and everything has been amazing. Recently, as my truck approached 75,000 miles, I opted to change my spark plugs as my 2 piece 3v plugs have such an issue with breaking. My local ford dealer (at least the one thats close to me that I would trust to take my truck to) had told me of their issues getting the motorcraft plugs out (they even kept a basket of broken spark plugs on their service desk). As such, I opted to try to the champion 7879 (I never thought a ford dealer wouldn't laugh at my idea to change them to champion, these guys thought it wasn't a bad an idea). I've had them in for probably 2500 miles, and so far they've done pretty well... however, my truck has started to develop a rough idle, only in gear and in park. I've tried bumping the idle speed up 50 rpm, and cleaned my MAF, to no real avail. What i'm wondering is there anything gryphon wise I might want to look at changing since i'm no longer running the factory plugs? I'm looking at spark advance mostly, something I normally wouldn't play with, or anything else?. I know our truck have a tendency to develop a rough idle, and this may just be something completely unrelated to this, just wondering if anybody had any ideas. Thanks!!!

BTW, anybody in the Athens- GA area, Crawford ford got all my spark plugs out no problem, and their charge for broken plugs is lower than anybody else within 100 miles.
