I have heard mention in several articles that sometimes the radio might need some peaking and tuning. I have a
Cobra 29 LX 40-Channel CB Radio

And as i rarely use it except when way off road in a group, and have never really been able to send out. I would like a suggestion if possible of either a shop to send it to, or to buy a new unit that it is operating at max.

Depending on the group, it's either FRS, CB or ham
