I made 5 runs, maybe 6 that day when it acted up. Right after that we had it checked along with the trans and was told it was okay. Also that same week I changed my fuel sending unit and had my injectors checked thinking it was a fuel issue.

Now same converter it goes to around 5500 off the line. Its hard to say because it happens very fast and I have to shift right away or it hits the rev limiter. There has to be 10-12 runs on it right now.
