Cleaning out the EGR ports and passages is a good start and will probably get you below 1045 on the test, after that it's on to the catalytic converter.

There is a good DIY on here in the DIY section.

 

NOx comes from high combustion temperatures, so EGR is a good start. Also you could retard your spark timing a bit (within the tolerance).
