My Z I just bought has an ECUtek tune, and it's runs fine but it runs fairly rich and the afr wanders a bit compared to my other car under low load (normal driving), so I wanted to tinker with it a bit. However, since ECUtek doesn't support end user tuning I wanted to get Uprev. Are there any issues with going from one tuner to another?

As others mentioned, EcuTek is the way to go. However if you do want to tune it yourself you will need UpRev. There is no harm in going from EcuTek to UpRev. You will however lose the EcuTek license. Unlike UpRev, EcuTek licenses does not transfer back to the dongle. So you will lose it.
