New to the forum, hoping I get it right.

I have an 2004.5 Ram 2500 with an 5.9 with an Six speed trans. I had my injectors changed at 175k miles, because of rough idle and running. I presently have 250k.

I was getting 22mpg prior to change out. After the injectors were changed my mpg dropped to 17mpg. The Bosh shop told me there is an break in period, but not how long it should take.

I would think 75k miles is an sufficient break in period.

Would it be worth it to go to a dealer and have the PCM reflashed and if so, anybody know what TSB I should ask for?
