My Friend with a modem question?

Downstream looks good but the upstream power level is right on the raggedy edge. The guy that installed my modem told me that anything higher than 55 dBmv would cause problems. (I'm at 53 dBmv with no issues).

Yup, the up stream is iffy, not much room for error. 56-57db will cause an automatic modem reboot to keep the modem from frying itself attempting to push too much power out the line. It'll be something to watch.

So his Downstream is fine and nothing to worry about any right? But his Upstream is kinda iffy. How abouts can he get his Upstream better....does he need to call Suddenlink or is there anything he can do about it?

Short of getting one of the plant guys/RF engineers looking into it, he'll just have to wait until it starts disconnecting him. That upstream level would usually be from a bad splitter/wire in the house (but the down levels look fine, so probably not), bad drop line, bad or out of calibration line amp, excessive distance to the first amp, or a LOT of interference on the line making the modem "shout" to be heard over it.

Again, you'd need to get a plant guy to look into it, but I have absolutely no idea how an end user would get ahold of one. :s Calling in will get you no where as they will just look at their screen, see your modem is online at the moment, and possibly offer a truck roll (which would also be slim to no help).

The numbers are not hard to correct if something inside is causing the drop. If there is any kind of splitter/attenuator on the line, at -5/+55 removing it would put the signal levels at a great level. Raising one number lowers the other. I.e. removing a 6dB loss splitter would put the downstream around 0 and the upstream around 50 if not into the upper 40s.
