Couple thoughts, one is you very well might be triggering the traction control, with that much power...are you sure that not it.
Another possibility is your battery is going bad, although I have not heard of this happening, it causes all sorts of funky problems sometimes. Good to get it load tested for free at Autozone, Advance Auto, etc.
As far as misfire, I forgot whether or not it sets codes, however I've had an ls1 misfire (frayed plug wire), and was detected on a particular cylinder with the HP Tuners scanner..

I had to read it twice.

My car is a 2008 corvette LS3 and is having some kind of issues. It was flashing a check engine light saying 02 sensor was bad so I replaced it and it flashed for a little bit longer then went off. It now flashes when I’m driving. Some ppl are saying it’s a misfire. I do have a loss of power, it don’t feel as quick. I make around 650whp and it feels less then stock and when u get on it if anything above 25 it flashes a code. idk what it is as it’s not throwing a code when I connect it to a reader - it says 0 codes detected idk what the problem is. any ideas? any ppl going thru it too?
