Nope. But if you can't find a spec, and don't want to use "darn tight" as a spec, try this:

If you are refering to the big mounting bolt torque specs I would recommend you throw the TJM bolts (mine were grade 5) in a scrap box and buy some grade 8 bolts to replace them with. Then torque the hell out of them, I went as tight as I could get with a breaker bar on the bolts that connect the bumper to the mount (the biggest ones). If you have to have a number I would guess I torqued my grade 8 bolts to 100-120 ft-lbs. Also place a star washer between the bumper and the mount, it will bite into the steel and help keep the bumper from sliding in those adjustment slots. Also pick up some grade 8 nylock nuts, or even better, steel lock nuts so they will stay tight.
A loose connection between the bumper and mount is IMHO the main cause of bending failure with the TJM bull bar as it is stessed by winching or by an impact. A tight connection will also lessen the damage to your fender as the bumper tends to slide up into it during an impact.
