Is something wrong with my LSD??

Well I don't think it's overheating because it did it on the 1st launch. Basically on my way home today I pulled off to an empty side street near an industrial area where there is no one. Only did 5 pulls. The drive time from work to this area was about 15min. Didn't do anything crazy on the drive over, just normal driving.

As for road conditions, not bumpy at all. Had a slight lean to it going from the higher left to the right, however the car always pulled left.

Also I should say this isn't the first time I've experienced this. There was an incident last year against a Z06, I'll just leave it at that, where I experienced the same problem. Had to shift into 2nd by 4k rpm and even in 2nd I let off half way through because I was sideways. I've also experienced the same thing at the start line of our auto-x course the one time I went. I usually just rolled out of the start and went into 2nd immediately and kept it there the whole run.

As for my car, from the first week of ownership I put on FI 18" CBE. This was the same exhaust from my 09 touring sport that I just swapped over. It did make a difference powerwise but nothing crazy to cause traction problems.

I thought about swapping diffs but honestly I'm probably going to be trading in the next year or two so not sure it's worth it. With the new C7 Vette coming, the next gen STI, and of course the next gen Z I'll probably be moving on from the 370z. So not sure it's worth the hassle of swapping diffs, not to mention here in Vegas there is only one place that can do it and I'm not sure I have full confidence in them.

I guess I'll try a fluid change in the next week or two and go from there.
