After upgrading my fuel pump to a bosch I have found that I am getting a small amount of black smoke on fast take off. I am assuming that it is now running a bit rich, however I thought that since I have not changed my
FPR, how is this possible? I thought the
FPR would keep the fuel flowing at the same rate no matter what pump was on the car? Could it be something else?
Cheers for the help
