4.56 gears

[Robts]

We'll I took longer than I wanted but I finally got my gears and a Detroit Truetrac installed. At 60mph I'm about 2150 RPM's ...Does this seem right. Should I get new tunes with this gear change?..

How is the shifting with the gear change? If it shifts good, you probably won't need one but if it's shifting a little goofy, you might have the tune redone with the new gears. What can happen is the truck thinks at 2150rpms, your going X mph, but really with the gear change your going "this" mph and it can get confused thinking it needs to shift at this mph but your only going this mph.... get it.... All in all, if it's running and shifting fine, don't worry about it, although you might reset the PCM to relearn.

The speed and rpm is pretty close to where I'm at. At 2150 rpms, I might be closer to 62 or 63 but my tires are slightly taller.
