Yea anything after the first 02 doesnt matter. One thing you should think about getting is a wideband. That 900 could be rich or it could be lean. But if youre leaking at the crossover I would put my money on lean. Also you need to get rid of the 4 degrees of KR. 1 degree of KR is worth roughly 5hp. You could be losing up to 20hp due to detonation. Also, your fuel trims should lock in at zero. That -1.5 means that its pulling fuel when you go WOT, which means its leaning the car out, which is probably causing your KR.
