Peugeot/Bosch even fitted a 3rd piston de-activation system on the HP pump to reduce bhp cost there at low injection demands, so they were really looking around for mpg gains and investing some money in such things.
Generally, you *can* get extra power and retain good economy. I drove my HDi hard and had 44mpg standard, 43mpg after stage 1 remap, and 42mpg with 150bhp and FMIC and driving like a loon everywhere
Thing is, once you get on motorways and cruise at sensible speeds then it doesn't really matter what you have done, the basic fuellings are very optimised and so if the bulk of your driving is in those conditions then they won't change much
I'd think about looking into recon injectors if you are doing 6k miles a month just generally. I assume your bill is around £700 a month or £8,400 a year, so if you found even 5% in injectors you'd save more in a year than the recon injectors cost. Also the remap would probably work better with recon injectors too.
No doubt your car is high mileage any way, more so because you are doing 6k miles a year

dave, trying to get intouch with you about getting mine done!???
