07 c6 ls2 WOT issue on freeway!

Ok guys I have a few questions, I was driving on the freeway yesterday in 102 degree weather for an hour or so

Water temp, oil temp, trans temp are all Fine and in normal range

Water temp - 210
Oil temp - 210-220
Trans temp - 190ish

So I'm coming up on my off ramp and already going about 60-70 mph and I punch it WOT and the car falls flat and doesn't accelerate at all but I can hear the engine revving.. Almost felt like I was In neutral for a sec...

I come to a complete stop at the light and go WOT again and it was fine.. Pulled great from 0-60 before slowing down again

So what gives?

I was in "s" mode no paddle shifting

I've heard a couple of other people experience a similar issue, but never found out if it recurred or if they got something fixed.

Occasionally, you get lucky and it turns out to be a one-time glitch that never returns.
Occasionally...

Not to change the subject but were you in traffic on the freeway or at cruising speed? 210º coolant temp seems high unless you were in a lot of traffic.

Traffic, maybe heat soak caused the car to just fall flat?

So adding the 160 stat will be a better upgrade?

Normal in traffic, yes. On the freeway mine is constant 196-198º and I have OEM T-stat. Having said that I don't think the temp had anything to do with the car not accelerating. I don't know what the cause of that would be.
