Did you significantly increase injector size above stock? How far is the drive to the shop? Big injectors can wash down the cylinder walls and dilute the oil. The PCM can pull out 15% excess fuel using the long term fuel corrections. After that, it’s hit or miss with the short terms.

Still stock injectors and about 60 miles

Shouldn’t be a problem.... but the bigger the cam is, the harder it could be to drive. You could face stalling, surge, fueling gets sloppy at low RPM with high overlap, etc.. Moderate cam shouldn't be a problem.
