probably too rich or not enough timing.

Try taking some fuel out of the boost multiplyer fuel table or give it more timing in that area of the map.

ditto. depending on what heads you have, I've had to take as much as 25% of the fuel out to clear it up. a better ignition system will also help.

lots of things. AFR mainly. j/k. I guess you mean at WOT. if so then it reads ~11.5-12.0 depends on how far you can push your combo before it begins to deto.

get a WB and a custom chip. it's cheaper than a new motor.
