Hpfp more misfires
11 f10 550 x drive 103k. I’ve changed the plugs and coils which have less than 200 miles on them. I changed both turbos to the alpina turbos with the turbo smart diverters. Before the install I had replaced the fuel pumps for the same misfire issue and it ran smooth no codes. . Now on the initial start up after getting the turbos installed, it threw codes for misfires again, and then dies after 30secs. What could this be from?
