well I just read another post in which they said the torque converter will balloon at 5400 RPM's so am I safe to guess that 5400 would be the highest to set the RPM?

If it starts to balloon at 5400 then why set it at 5400. I would set it at 5000-5200.

Is the stock setting 5250? But I thought I have heard other people say that it is safe to increase it, so does the torque converter really begin to balloon at 5400? I guess I am just trying to find out some information more so then anything.

I've got the 4.6 with a custom tune and the truck shifts around 5500 at WOT. I wouldn't go that high though. The only reason I'm leaving it is because I dont get up there very often. 5500 is what I would set the rev limiter and make the shift 200 RPM lower or more if it shifts funny.
