new (standard) replacement nozzle Q!

[ELVIS]

have a 5 pot audi (2.5 tdi) . have booked it into a well respected local specialist wo is going to completely recon/rebuild them. 2 stage injectors so will check + correct breaking pressures if needed etc etc
   what sort of improvement can i expect from a well built set of replacement nozzles ( genuine bosch not chinese cr*p!) will give me over mine now ? they have 160k miles on them . improved performance/ smoothness/mpg ? anything noticable ?  just curiosity really.

all of the above.  just setting the breaking pressure alone (if the injectors are that far off) will do most of the above.

is it a kick in the a$$ " OMG" difference or just a pleasant smile difference ?
