Calibration takes places less than 1 min on ista+. Now I don't believe it will do anything for rought idle but the since you say you can't tell if it's the nj road or the car I think it's an easy and quick to rule it TC before doing further diagnosis. As far as the injectors I'm not sure about the test plans but some have used the techron to see if anything changes to determine any problems in that component. Both easy and quick before sending it to the shop.
