I would say yes. I had my nozzles fitted at the same time as my remap. We did run it before, and it was running really bad. The new map sorted it though and it drives great. I have the .216 nozzles fitted, which are larger than the ones your looking at, I don't know how much differene it would make. I am sure somebody here who knows alot more than I do will be able to help.
 
Ok well I've sent an email off to OBD in Ballymena asking about what output they could squeeze from the uprated injectors, and whether or not they could "map them in"
