I'm not sure how to adust wide open throttle with the predator. Should I make it richer or leaner? stock engine with Diablo Tune and K&N air filter in air box.

Im a little out of your area but the guys that work on my goat know alot about working with the preditor.

I wouldn't recommend making changes like that unless you were on a dyno with an O2 sensor. You could do SERIOUS damage to your engine by adjusting a/f ratios. I don't know if there's enough leeway in the predator's tuning to do much damage, but it can be quite dangerous for an untrained person to mess around with such things.
