Injectors, Blues and Blacks
I posted the flow data from my blacks in the classifieds and in the interest of the knowledge base here's the flow sheet on the blues. I had both sets checked by Marren Fuel Injector Service. Discuss.

Les, Thanks for sharing the info. The info I have from Bosch coincides with your numbers. The blue injectors that are used on 06 E55 and 06 Xfire supposed to flow 15% better than the black injectors. From the data that you supplied it looks like the black injectors tested at 43PSI (about 80% utilization) are 410 cc while the blue injectors at 43 PSI tested at 460 cc.
BTW, I have been running the blue injectors for close to a year now. No issues. EPC also lists the blue injectors as the replacement part for the older black injectors.

More than a few Crossfires have 5 blacks and 1 blue and seem to be running great. I race my car, it's my hobby, and I honestly didn't notice any difference in performance. That said, I didn't data log with the blacks so slight differences in AFR's could have occurred. My best 1/4 mile time with the blacks was 12.04. With the blues 12.04. Lately I've made some changes so the car is faster. Same tune for years.
