with flash on...
Like i said, they dont look to bad to me, so i dont know why im having alot of hiccuping on partial throttle every once in a while and why im missing up top on ful throttle, but i can boost just fine on partial throttle. Hmmm....

Thats weird as hell, i figured one of my injectors was stuck open or something, causing me to run really rich, and teh ecu going into closed loop and running like crap. Hmmm, wonder what i could be then...

Rich at cruise for sure.
Damn those are tall plugs, are they like heat range 4 or something lol
Your on BBKA's map right? His did the same thing, like it didnt wanna run in closed loop, and just stayed in openloop. I know Pat has been making changes to his map since he got a WB. Maybe he'll post it here.

Plug reading does you no good unless you do it right...
To get a good reading of your combustion chamber events you must first- Go wide open throttle (WOT) for several seconds, about 4-5 seconds all out. Then, let off, allow the revs to drop and shut the car off. Remove your plugs (recommended after engine is below 100oF.) Dark to light Tan= Good combustion. I forgot exactly what other colors mean, I may look it back up and post. Probably not.
This is the way we read spark plugs after dyno pulls. WOT, then shut it down and let it cool for a few minutes, take reading per cylinder, fix problem.
