I think I would have $hit my pants if my engine went over 7k and still didn't hit the Rev limiter. That limiter is there for a reason. Hope it gets fixed for you.

With a new tune a lot of one-time incorrect gauge readings have been reported as the ECU and transmission module are relearning... It is possible the engine did not over-rev.. don't know, wasn't there...But I have just been on the phone directly with a tuner (thanks Dave!!) for LMS for about an hour on other issues... so I asked...and he relates they remove the speed limiter (your SHO, at least if it's a '13 is governed at 130mph), and adjust shift-point and boost duration as I said before, but they don't change the shutdown safety parameters of the ECU

FYI...

The 2013 SHO speed limiter is 140 mph

It does seem like a couple of unusual things.  If you have aftermarket wheels and tires there might be some factors for the wheel hop there.. but. I'd flash back to stock to see if the events continue after a learning period first, then either way talk to LMS to see if a mod or just a new copy of the tune might help (what they think) and go to the dealer after that to exclude a system fault in hardware or software.  Just how I would approach it.

Spoke with Anthony today. After it all he suggested reflashing ecu. Thought being maybe the shifting was caused by ecu not having clean data. The rpm, he insist all of their tunes will shift at 6600 even if driver doesn't or other odd things happen.

He contends that possibly any other issues may be issues with car mechanical or electrical. Sounds like pass the buck, but who am I?

I will be reflashing as he suggested. Then hit a couple 1/4 mile runs immediately to see how car behaves and go from there.

Wheels are stock 19" so "shouldn't" be an issue.
