Possible traction control issues.

So every now and again, pulling away from a light, not using full throttle, or anything like that, the tires chirp, and such. Something that seems a little odd to me, given im not wooding it trying to make them do that.
Now i have had the TSB done for the rear leafs, and have installed 5100's all around, running the front at .85
Would this be enough change to need me to get the settings re-calibrated, or should it not be an issue, and im just not used to the jump in power? (came from a many year old 4runner)
Thanks.

 

Eh. don't think its the paint, but could be.. Not much left to be on at the streets its happened at. I'll keep an eye on that however.

 

I dropped my tire pressures down for the summer since I'm not commuting as much. Fronts at 32, backs at 30. I noticed I have a lot more squeal from my tires on take-off and in corners than when I was running them at 36 and 34.
