I had my injectors with the new Bosio nozzles pop tested after I thoroughly cleaned them by Diesel Injection Services, a certified Bosch center, here in Cincinnati. They said you shouldn't have any problems with these. They all tested at right around stock recommendation of 115 bar. They didn't charge me anything! The 240d runs much better, smoother and with what I perceive as improved torque. I still think the IP needs timed and adjusted, a little nailing at idle and some white smoke, but not nearly as bad as pre Bosio. I think fuel economy should be improved as well, haven't finished this tank yet, but I've gone 200miles on a half (14 gal) tank. Prior to new nozzles was 20-25 mi less.
