Well I do not see any significant wheelspeed in that graph at all. Would like to see your AFR line however. My guess is if you have the ability to overlay the AFR's and Fuel pressure to that graph you may find a trend there. Also acceleration G's will show if you are seeing any excess wheelspin. That graph you show does not really show anything more than a tad bit more wheelspeed, not really spin. Seems to be pulling motor down and then lazily accelerating in first. My guess is there is a fuel issue causing it.
