I don't doubt for 1 second siemens are a easier more controllable injector I just don't see the point of ditching perfectly good useable injectors, that can still give ace emissions and performance, my greys had enough resolution for a mot pass and 100% perfect running at 0.97% CO, 137ppm with 200,000 mile son at the mot test, and was NOT adjusted for the mot, and was NOT on closed loop.
